David Chinner 40095b64f5 [XFS] Sleeping with the ilock waiting for I/O completion is Bad. ... Recent fixes to the filesystem freezing code introduced a vn_iowait call in the middle of the sync code. Unfortunately, at the point where this call was added we are holding the ilock. The ilock is needed by I/O completion for unwritten extent conversion and now updating the file size. Hence I/o cannot complete if we hold the ilock while waiting for I/O completion. Fix up the bug and clean the code up around it.
