Not sure if it is related to the patch or not, but it never returns from
wait_for_completion_io(&wait) in blkdev_issue_flush():

# ps axl | awk '$10 ~ /D\+/'
4     0   938   879  20   0 111216   656 blkdev D+   pts/1      0:00 fdisk/dev/sda

# cat /proc/938/stack
[<ffffffff812a8a5c>] blkdev_issue_flush+0xfc/0x160
[<ffffffff811ac606>] blkdev_fsync+0x96/0xc0

[<ffffffff81611582>] system_call_fastpath+0x16/0x1b
[<ffffffffffffffff>] 0xffffffffffffffff

Any ideas?

Thanks!
