Subject[PATCH 0/7] Loop device bug fix
This patchset fix several loop device bugs.

Patch #1 fix non-atomic updating block device size. It also prepares for
a later dead lock patch.

Patch #2 is a trivial clean up about block device.

The rest of the patchset are loop device fix:

#3 - fix a dead loop
#4 - fix a race-like problem
#5 - a little clean up based on #3 and #4
#6 - fix a user triggable oops
#7 - avoid loop device size being messed up by parameters from users

Guo Chao (7):
block: use i_size_write() in bd_set_size()
block: remove redundant check to bd_openers
loopdev: fix a dead lock
loopdev: update block device size in loop_set_status()
loopdev: move common code into loop_figure_size()
loopdev: remove an user triggable oops
loopdev: ignore negative offset when calculate loop device size
