2006-02-24[PATCH] flags parameter for linkatUlrich Drepper
I'm currently at the POSIX meeting and one thing covered was the incompatibility of Linux's link() with the POSIX definition. The name. Linux does not follow symlinks, POSIX requires it does. Even if somebody thinks this is a good default behavior we cannot change this because it would break the ABI. But the fact remains that some application might want this behavior. We have one chance to help implementing this without breaking the behavior. For this we could use the new linkat interface which would need a new flags parameter. If the new parameter is AT_SYMLINK_FOLLOW the new behavior could be invoked. I do not want to introduce such a patch now. But we could add the parameter now, just don't use it. The patch below would do this. Can we get this late patch applied before the release more or less fixes the syscall API?

2006-02-22Revert mount/umount uevent removalGreg Kroah-Hartman
This change reverts the 033b96fd30db52a710d97b06f87d16fc59fee0f1 commit from Kay Sievers that removed the mount/umount uevents from the kernel. Some older versions of HAL still depend on these events to detect when a new device has been mounted. These events are not correctly emitted, and are broken by design, and so, should not be relied upon by any future program. Instead, the /proc/mounts file should be polled to properly detect this kind of event. A feature-removal-schedule.txt entry has been added, noting when this interface will be removed from the kernel.

2006-02-17[PATCH] fix deadlock in ext2Peter Staubach
Fix a deadlock possible in the ext2 file system implementation. This deadlock occurs when a file is removed from an ext2 file system which was mounted with the "sync" mount option. The problem is that ext2_xattr_delete_inode() was invoking the routine, sync_dirty_buffer(), using a buffer head which was previously locked via lock_buffer(). The first thing that sync_dirty_buffer() does is to lock the buffer head that it was passed. It does this via lock_buffer(). Oops. The solution is to unlock the buffer head in ext2_xattr_delete_inode() before invoking sync_dirty_buffer(). This makes the code in ext2_xattr_delete_inode() obey the same locking rules as all other callers of sync_dirty_buffer() in the ext2 file system implementation.

2006-02-15[GFS2] Fix for lock recursion problem for internal filesSteven Whitehouse
Two internal files which are read through the gfs2_internal_read() routine were already locked when the routine was called and this do not need locking at the redapages level. This patch introduces a struct file which is used as a sentinal so that readpage will only perform locking in the case that the struct file passed to it is _not_ equal to this sentinal. Since the comments in the generic kernel code indicate that the struct file will never be used for anything other than passing straight through to readpage(), this should be ok.

2006-02-14[PATCH] NLM: Fix the NLM_GRANTED callback checksTrond Myklebust
If 2 threads attached to the same process are blocking on different locks on different files (maybe even on different servers) but have the same lock arguments (i.e. same offset+length - actually quite common, since most processes try to lock the entire file) then the first GRANTED call that wakes one up will also wake the other. Currently when the NLM_GRANTED callback comes in, lockd walks the list of blocked locks in search of a match to the lock that the NLM server has granted. Although it checks the lock pid, start and end, it fails to check the filehandle and the server address. By checking the filehandle and server IP address, we ensure that this only happens if the locks truly are referencing the same file.

2006-02-14[GFS2] Put back O_DIRECT supportSteven Whitehouse
This patch adds back O_DIRECT support with various caveats attached: 1. Journaled data can be read via O_DIRECT since its now the same on disk format as normal data files. 2. Journaled data writes with O_DIRECT will be failed sliently back to normal writes (should we really do this I wonder or should we return an error instead?) 3. Stuffed files will be failed back to normal buffered I/O 4. All the usual corner cases (write beyond current end of file, write to an unallocated block) will also revert to normal buffered I/O. The I/O path is slightly odd as reads arrive at the page cache layer with the lock for the file already held, but writes arrive unlocked. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-13[PATCH] reiserfs: fix potential (unlikely) oops in reiserfs_get_aclJeff Mahoney

2006-02-13[GFS2] Change ondisk format (hopefully for the last time)Steven Whitehouse
There were one or two fields in structures which didn't get changed last time back to their gfs1 sizes and alignments. One or two constants have also changed back to their original values which were missed the first time. Its possible that indirect pointer blocks might need to change. If they don't we'll have to rewrite them all on upgrade due to a change in the amount of padding that they use. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-13[GFS2] Fix for root inode ref count bugSteven Whitehouse
Umount is now working correctly again. The bug was due to not getting an extra ref count when mounting the fs. We should have bumped it by two (once for the internal pointer to the root inode from the super block and once for the inode hanging off the dcache entry for root). Also this patch tidys up the code dealing with looking up and creating inodes. We now pass Linux inodes (with gfs2_inodes attached) rather than the other way around and this reduces code duplication in various places. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-12[PATCH] reiserfs: disable automatic enabling of reiserfs inode attributesJeff Mahoney
Unfortunately, the reiserfs_attrs_cleared bit in the superblock flag can lie. File systems have been observed with the bit set, yet still contain garbage in the stat data field, causing unpredictable results. This patch backs out the enable-by-default behavior. It eliminates the changes from: d50a5cd860ce721dbeac6a4f3c6e42abcde68cd8, and ef5e5414e7a83eb9b4295bbaba5464410b11e030.
