[pnfs] [PATCH 0/2] layout commit changes

[Benny Halevy]

The following two patches implement changes we need for
layout commit.  The first patch one adds logic on the client
side to mark the inode for layout commit on the sync and async
write paths and to send the layoutcommit before close.
The second patch adds a layout_commit export op and
calls it rather than notify_change if the file system
implemented it (we need it in order to avoid blocking
indefinitely in the setattr patch)
