[PATCH 0/8 v3] xfs: fix direct IO completion issues

[Dave Chinner]

Hi folks,

Versions 3 of the DIO write completion fixes, v2 was here:

http://oss.sgi.com/archives/xfs/2015-04/msg00129.html

This version fixes the spelling mistakes Brian noticed, re-adds a
couple of comments that were incorrectly removed, re-adds an assert
in the !ioend path inside xfs_end_io_direct_write() and cleans up
the setting of the buffer_defer_completion flag so that it's set
when we allocate the ioend for defered completion.

Comments, thoughts and testing all wlecome.

-Dave.
