[xfs-masters] [patch 1/2] fs/xfs_buf: replace schedule_timeout() with msleep()

[domen@xxxxxxxxxxxx]

Use msleep() instead of schedule_timeout() to guarantee the task
delays as expected. The current code uses TASK_INTERRUPTIBLE, but does not check
for signals, so I believe the change to msleep() is appropriate.
