gfs2: Extended attribute readahead
When gfs2 allocates an inode and its extended attribute block next to each other at inode create time, the inode's directory entry indicates that in de_rahead. In that case, we can readahead the extended attribute block when we read in the inode. Signed-off-by: Andreas Gruenbacher <agruenba@redhat.com> Signed-off-by: Bob Peterson <rpeterso@redhat.com>
