2008-02-08dm: refactor dm_suspend completion waitMilan Broz
Move completion wait to separate function Signed-off-by: Milan Broz <mbroz@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2008-02-08dm: split dm_suspend io_lock hold into twoMilan Broz
Change io_locking to allow processing flush in separate thread. Because we have DMF_BLOCK_IO already set, any possible new ios are queued in dm_requests now. In the case of interrupting previous wait there can be more ios queued (we unlocked io_lock for a while) but this is safe.

2008-02-07i915: Fix GR register array size off-by-one bugJesse Barnes

2008-02-07BKL-removal: Use unlocked_ioctl for jfsAndi Kleen
Convert jfs_ioctl over to not use the BKL. The only potential race I could see was with two ioctls in parallel changing the flags and losing the updates. Use the i_mutex to protect against this. Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com>
2008-02-07sysfs: remove BUG_ON() from sysfs_remove_group()Greg Kroah-Hartman

2008-02-07Driver core: Revert "Fix Firmware class name collision"Michael E Brown
This reverts commit 109f0e93b6b728f03c1eb4af02bc25d71b646c59. The original patch breaks BIOS updates on all Dell machines. The path to the firmware file for the dell_rbu driver changes, which breaks all of the userspace tools which rely on it. Note that this patch re-introduces a problem with i2c name collision that was previously fixed by this patch.

2008-02-07Block: Fix whole_disk attribute bugGreg Kroah-Hartman
The "whole_disk" attribute was not properly converted in the block device conversion earlier, and if the file is read, bad things can happen. This patch fixes this, making the attribute an empty one, preserving the original functionality. Many thanks to David Miller for finding this, and pointing me in the proper place within the block code to look. Acked-by: David S.
