David Howells 54919f94ec xfs: Provide a splice-read wrapper 
Provide a splice_read wrapper for XFS.  This does a stat count and a
shutdown check before proceeding, then emits a new trace line and locks the
inode across the call to filemap_splice_read() and adds to the stats
afterwards.  Splicing from direct I/O or DAX is handled by the caller.
