Pull second xfs update from Ben Myers:
"There are a couple of patches that I wasn't quite sure about in time
for our initial 3.13 pull request, a bugfix, and an update to add Dave
to MAINTAINERS:
Here we have a performance fix for inode iversion, increased inode
cluster size for v5 superblock filesystems, a fix for error handling
in xfs_bmap_add_attrfork, and a MAINTAINERS update to add Dave"
