+Managing bug reports
+--------------------
+
+One of the best ways to put into practice your hacking skills is by fixing
+bugs reported by other people. Not only you will help to make the kernel
+more stable, you'll learn to fix real world problems and you will improve
+your skills, and other developers will be aware of your presence. Fixing
+bugs is one of the best ways to get merits among other developers, because
+not many people like wasting time fixing other people's bugs.

-6. FAQ
+6. MSI quirks
+
+Several PCI chipsets or devices are known to not support MSI.
+The PCI stack provides 3 possible levels of MSI disabling:
+* on a single device
+* on all devices behind a specific bridge
+* globally
+
+6.1. Disabling MSI on a single device
+
+Under some circumstances, it might be required to disable MSI on a
+single device, It may be achived by either not calling pci_enable_msi()
+or all, or setting the pci_dev->no_msi flag before (most of the time
+in a quirk).
+
+6.2. Disabling MSI below a bridge
+
+The vast majority of MSI quirks are required by PCI bridges not
+being able to route MSI between busses. In this case, MSI have to be
+disabled on all devices behind this bridge. It is achieves by setting
+the PCI_BUS_FLAGS_NO_MSI flag in the pci_bus->bus_flags of the bridge
+subordinate bus. There is no need to set the same flag on bridges that
+are below the broken brigde. When pci_enable_msi() is called to enable
+MSI on a device, pci_msi_supported() takes care of checking the NO_MSI
+flag in all parent busses of the device.
+
+Some bridges actually support dynamic MSI support enabling/disabling
+by changing some bits in their PCI configuration space (especially
+the Hypertransport chipsets such as the nVidia nForce and Serverworks
+HT2000). It may then be required to update the NO_MSI flag on the
+corresponding devices in the sysfs hierarchy. To enable MSI support
+on device "0000:00:0e", do:
+
+ echo 1 > /sys/bus/pci/devices/0000:00:0e/msi_bus
+
+To disable MSI support, echo 0 instead of 1. Note that it should be
+used with caution since changing this value might break interrupts.
+
+6.3. Disabling MSI globally
+
+Some extreme cases may require to disable MSI globally on the system.
+For now, the only known case is a Serverworks PCI-X chipsets (MSI are
+not supported on several busses that are not all connected to the
+chipset in the Linux PCI hierarchy). In the vast majority of other
+cases, disabling only behind a specific bridge is enough.
+
+For debugging purpose, the user may also pass pci=nomsi on the kernel
+command-line to explicitly disable MSI globally. But, once the appro-
+priate quirks are added to the kernel, this option should not be
+required anymore.
+
+6.4. Finding why MSI cannot be enabled on a device
+
+Assuming that MSI are not enabled on a device, you should look at
+dmesg to find messages that quirks may output when disabling MSI
+on some devices, some bridges or even globally.
+Then, lspci -t gives the list of bridges above a device. Reading
+/sys/bus/pci/devices/0000:00:0e/msi_bus will tell you whether MSI
+are enabled (1) or disabled (0). In 0 is found in a single bridge
+msi_bus file above the device, MSI cannot be enabled.
+
+7. FAQ
Q1. Are there any limitations on using the MSI?

+Ext4 Filesystem
+===============
+
+This is a development version of the ext4 filesystem, an advanced level
+of the ext3 filesystem which incorporates scalability and reliability
+enhancements for supporting large filesystems (64 bit) in keeping with
+increasing disk capacities and state-of-the-art feature requirements.
+
+Mailing list: linux-ext4@vger.kernel.org
+
+
+1. Quick usage instructions:
+===========================
+
+ - Grab updated e2fsprogs from
+ ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs-interim/
+ This is a patchset on top of e2fsprogs-1.39, which can be found at
+ ftp://ftp.kernel.org/pub/linux/kernel/people/tytso/e2fsprogs/
+
+ - It's still mke2fs -j /dev/hda1
+
+ - mount /dev/hda1 /wherever -t ext4dev
+
+ - To enable extents,
+
+ mount /dev/hda1 /wherever -t ext4dev -o extents
+
+ - The filesystem is compatible with the ext3 driver until you add a file
+ which has extents (ie: `mount -o extents', then create a file).
+
+ NOTE: The "extents" mount flag is temporary. It will soon go away and
+ extents will be enabled by the "-o extents" flag to mke2fs or tune2fs
+
+ - When comparing performance with other filesystems, remember that
+ ext3/4 by default offers higher data integrity guarantees than most. So
+ when comparing with a metadata-only journalling filesystem, use `mount -o
+ data=writeback'. And you might as well use `mount -o nobh' too along
+ with it. Making the journal larger than the mke2fs default often helps
+ performance with metadata-intensive workloads.
+
+2. Features
+===========
+
+2.1 Currently available
+
+* ability to use filesystems > 16TB
+* extent format reduces metadata overhead (RAM, IO for access, transactions)
+* extent format more robust in face of on-disk corruption due to magics,
+* internal redunancy in tree
+
+2.1 Previously available, soon to be enabled by default by "mkefs.ext4":
+
+* dir_index and resize inode will be on by default
+* large inodes will be used by default for fast EAs, nsec timestamps, etc
+
+2.2 Candidate features for future inclusion
+
+There are several under discussion, whether they all make it in is
+partly a function of how much time everyone has to work on them:
+
+* improved file allocation (multi-block alloc, delayed alloc; basically done)
+* fix 32000 subdirectory limit (patch exists, needs some e2fsck work)
+* nsec timestamps for mtime, atime, ctime, create time (patch exists,
+ needs some e2fsck work)
+* inode version field on disk (NFSv4, Lustre; prototype exists)
+* reduced mke2fs/e2fsck time via uninitialized groups (prototype exists)
+* journal checksumming for robustness, performance (prototype exists)
+* persistent file preallocation (e.g for streaming media, databases)
+
+Features like metadata checksumming have been discussed and planned for
+a bit but no patches exist yet so I'm not sure they're in the near-term
+roadmap.
+
+The big performance win will come with mballoc and delalloc. CFS has
+been using mballoc for a few years already with Lustre, and IBM + Bull
+did a lot of benchmarking on it. The reason it isn't in the first set of
+patches is partly a manageability issue, and partly because it doesn't
+directly affect the on-disk format (outside of much better allocation)
+so it isn't critical to get into the first round of changes. I believe
+Alex is working on a new set of patches right now.
+
+3. Options
+==========
+
+When mounting an ext4 filesystem, the following option are accepted:
+(*) == default
+
+extents ext4 will use extents to address file data. The
+ file system will no longer be mountable by ext3.
+
+journal=update Update the ext4 file system's journal to the current
+ format.
+
+journal=inum When a journal already exists, this option is ignored.
+ Otherwise, it specifies the number of the inode which
+ will represent the ext4 file system's journal file.
+
+journal_dev=devnum When the external journal device's major/minor numbers
+ have changed, this option allows the user to specify
+ the new journal location. The journal device is
+ identified through its new major/minor numbers encoded
+ in devnum.
+
+noload Don't load the journal on mounting.
+
+data=journal All data are committed into the journal prior to being
+ written into the main file system.
+
+data=ordered (*) All data are forced directly out to the main file
+ system prior to its metadata being committed to the
+ journal.
+
+data=writeback Data ordering is not preserved, data may be written
+ into the main file system after its metadata has been
+ committed to the journal.
+
+commit=nrsec (*) Ext4 can be told to sync all its data and metadata
+ every 'nrsec' seconds. The default value is 5 seconds.
+ This means that if you lose your power, you will lose
+ as much as the latest 5 seconds of work (your
+ filesystem will not be damaged though, thanks to the
+ journaling). This default value (or any low value)
+ will hurt performance, but it's good for data-safety.
+ Setting it to 0 will have the same effect as leaving
+ it at the default (5 seconds).
+ Setting it to very large values will improve
+ performance.
+
+barrier=1 This enables/disables barriers. barrier=0 disables
+ it, barrier=1 enables it.
+
+orlov (*) This enables the new Orlov block allocator. It is
+ enabled by default.
+
+oldalloc This disables the Orlov block allocator and enables
+ the old block allocator. Orlov should have better
+ performance - we'd like to get some feedback if it's
+ the contrary for you.
+
+user_xattr Enables Extended User Attributes. Additionally, you
+ need to have extended attribute support enabled in the
+ kernel configuration (CONFIG_EXT4_FS_XATTR). See the
+ attr(5) manual page and http://acl.bestbits.at/ to
+ learn more about extended attributes.
+
+nouser_xattr Disables Extended User Attributes.
+
+acl Enables POSIX Access Control Lists support.
+ Additionally, you need to have ACL support enabled in
+ the kernel configuration (CONFIG_EXT4_FS_POSIX_ACL).
+ See the acl(5) manual page and http://acl.bestbits.at/
+ for more information.
+
+noacl This option disables POSIX Access Control List
+ support.
+
+reservation
+
+noreservation
+
+bsddf (*) Make 'df' act like BSD.
+minixdf Make 'df' act like Minix.
+
+check=none Don't do extra checking of bitmaps on mount.
+nocheck
+
+debug Extra debugging information is sent to syslog.
+
+errors=remount-ro(*) Remount the filesystem read-only on an error.
+errors=continue Keep going on a filesystem error.
+errors=panic Panic and halt the machine if an error occurs.
+
+grpid Give objects the same group ID as their creator.
+bsdgroups
+
+nogrpid (*) New objects have the group ID of their creator.
+sysvgroups
+
+resgid=n The group ID which may use the reserved blocks.
+
+resuid=n The user ID which may use the reserved blocks.
+
+sb=n Use alternate superblock at this location.
+
+quota
+noquota
+grpquota
+usrquota
+
+bh (*) ext4 associates buffer heads to data pages to
+nobh (a) cache disk block mapping information
+ (b) link pages into transaction to provide
+ ordering guarantees.
+ "bh" option forces use of buffer heads.
+ "nobh" option tries to avoid associating buffer
+ heads (supported only for "writeback" mode).
+
+
+Data Mode
+---------
+There are 3 different data modes:
+
+* writeback mode
+In data=writeback mode, ext4 does not journal data at all. This mode provides
+a similar level of journaling as that of XFS, JFS, and ReiserFS in its default
+mode - metadata journaling. A crash+recovery can cause incorrect data to
+appear in files which were written shortly before the crash. This mode will
+typically provide the best ext4 performance.
+
+* ordered mode
+In data=ordered mode, ext4 only officially journals metadata, but it logically
+groups metadata and data blocks into a single unit called a transaction. When
+it's time to write the new metadata out to disk, the associated data blocks
+are written first. In general, this mode performs slightly slower than
+writeback but significantly faster than journal mode.
+
+* journal mode
+data=journal mode provides full data and metadata journaling. All new data is
+written to the journal first, and then to its final location.
+In the event of a crash, the journal can be replayed, bringing both data and
+metadata into a consistent state. This mode is the slowest except when data
+needs to be read from and written to disk at the same time where it
+outperforms all others modes.
