Drivers: misc: remove __dev* attributes.

2013-01-03T23:57:16Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand. Cc: Bill Pemberton Signed-off-by: Greg Kroah-Hartman

workqueue: deprecate flush[_delayed]_work_sync()

2012-08-20T21:51:24Z

flush[_delayed]_work_sync() are now spurious. Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away. This patch doesn't make any functional difference.

powerpc: Remove some of the legacy iSeries specific device drivers

2012-03-15T22:28:05Z

These drivers are specific to the PowerPC legacy iSeries platform and their Kconfig is specified in arch/powerpc. Legacy iSeries is being removed, so these drivers can no longer be selected. Cc: Jens Axboe Signed-off-by: Stephen Rothwell Signed-off-by: Benjamin Herrenschmidt

cdrom: move shared static to cdrom_device_info

2012-02-08T19:03:14Z

The keeplocked variable in the cdrom driver is shared across multiple drives, but set in per-device ioctls. Move it to the per-device struct, avoiding that the setting on one drive affects the driver's behavior when closing another. [ Impact: limit udev's confusion to one drive when a CD burning program unlocks the CD door at the end of burning. ] Signed-off-by: Paolo Bonzini Signed-off-by: Jens Axboe

cdrom: use copy_to_user() without the underscores

2012-02-06T09:20:45Z

"nframes" comes from the user and "nframes * CD_FRAMESIZE_RAW" can wrap on 32 bit systems. That would have been ok if we used the same wrapped value for the copy, but we use a shifted value. We should just use the checked version of copy_to_user() because it's not going to make a difference to the speed. Cc: stable@vger.kernel.com Signed-off-by: Dan Carpenter Signed-off-by: Jens Axboe

block: add and use scsi_blk_cmd_ioctl

2012-01-14T23:07:24Z

Introduce a wrapper around scsi_cmd_ioctl that takes a block device. The function will then be enhanced to detect partition block devices and, in that case, subject the ioctls to whitelisting.

module_param: make bool parameters really bool (drivers & misc)

2012-01-12T23:02:20Z

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab Signed-off-by: Rusty Russell

fs: move code out of buffer.c

2012-01-04T03:54:07Z

Move invalidate_bdev, block_sync_page into fs/block_dev.c. Export kill_bdev as well, so brd doesn't have to open code it. Reduce buffer_head.h requirement accordingly. Removed a rather large comment from invalidate_bdev, as it looked a bit obsolete to bother moving. The small comment replacing it says enough.

drivers/cdrom/cdrom.c: relax check on dvd manufacturer value

2011-08-02T10:43:50Z

The report has an ISO which has a very long manufacturer ID. It seems that Linux is wrong, not the ISO maker. Relax the check for the length of this field: emit a warning and truncate the incoming data to 2048 bytes rather than rejecting the entire thing. dvd_manufact.value isn't null-terminated. I'm not even sure if it's a string. The kernel doesn't apepar to use it anyway.

block: fix mismerge of the DISK_EVENT_MEDIA_CHANGE removal

2011-06-01T20:29:19Z

Jens' back-merge commit 698567f3fa79 ("Merge commit 'v2.6.39' into for-2.6.40/core") was incorrectly done, and re-introduced the DISK_EVENT_MEDIA_CHANGE lines that had been removed earlier in commits - 9fd097b14918 ("block: unexport DISK_EVENT_MEDIA_CHANGE for legacy/fringe drivers") - 7eec77a1816a ("ide: unexport DISK_EVENT_MEDIA_CHANGE for ide-gd and ide-cd") because of conflicts with the "g->flags" updates near-by by commit d4dc210f69bc ("block: don't block events on excl write for non-optical devices") As a result, we re-introduced the hanging behavior due to infinite disk media change reports. Tssk, tssk, people! Don't do back-merges at all, and *definitely* don't do them to hide merge conflicts from me - especially as I'm likely better at merging them than you are, since I do so many merges.
