block/ioctl.c and fs/partition/check.c: check value returned by add_partition()

2008-07-25T17:53:44+00:00

Now that add_partition() has been aught to propagate errors, let's check them.

compat_ioctl: move common block ioctls to compat_blkdev_ioctl

2007-10-10T07:26:00+00:00

Make compat_blkdev_ioctl and blkdev_ioctl reflect the respective
native versions. This is somewhat more efficient and makes it easier
to keep the two in sync.

Also get rid of the bogus handling for broken_blkgetsize and the
duplicate entry for BLKRASET.

mm: remove destroy_dirty_buffers from invalidate_bdev()

2007-05-07T19:12:55+00:00

Remove the destroy_dirty_buffers argument from invalidate_bdev(), it hasn't
been used in 6 years (so akpm says).

find * -name \*.[ch] | xargs grep -l invalidate_bdev |
while read file; do
	quilt add $file;
	sed -ie 's/invalidate_bdev(\([^,]*\),[^)]*)/invalidate_bdev(\1)/g' $file;
done

Annotate BLKPG_DEL_PARTITION's bd_mutex locking and add a little comment
clarifying the bd_mutex locking, because I confused myself and initially
thought the lock order was wrong too.

[PARTITION]: Add whole_disk attribute.

2007-02-11T07:50:00+00:00

Some partitioning systems create special partitions that
span the entire disk.  One example are Sun partitions, and
this whole-disk partition exists to tell the firmware the
extent of the entire device so it can load the boot block
and do other things.

Such partitions should not be treated as normal partitions,
because all the other partitions overlap this whole-disk one.
So we'd see multiple instances of the same UUID etc. which
we do not want.  udev and friends can thus search for this
'whole_disk' attribute and use it to decide to ignore the
partition.

[PATCH] dm: export blkdev_driver_ioctl

2006-10-03T15:04:13+00:00

Export blkdev_driver_ioctl for device-mapper.

If we get as far as the device-mapper ioctl handler, we know the ioctl is not
a standard block layer BLK* one, so we don't need to check for them a second
time and can call blkdev_driver_ioctl() directly.

[PATCH] lockdep: annotate the BLKPG_DEL_PARTITION ioctl

2006-07-15T04:53:53+00:00

The delete partition IOCTL takes the bd_mutex for both the disk and the
partition; these have an obvious hierarchical relationship and this patch
annotates this relationship for lockdep.
