Dave Chinner f9b395a8ef xfs: align initial file allocations correctly ... The function xfs_bmap_isaeof() is used to indicate that an allocation is occurring at or past the end of file, and as such should be aligned to the underlying storage geometry if possible. Commit 27a3f8f ("xfs: introduce xfs_bmap_last_extent") changed the behaviour of this function for empty files - it turned off allocation alignment for this case accidentally. Hence large initial allocations from direct IO are not getting correctly aligned to the underlying geometry, and that is cause write performance to drop in alignment sensitive configurations. Fix it by considering allocation into empty files as requiring aligned allocation again.
