Merge branch 'afs-dh' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull AFS updates from Al Viro: "The AFS series posted by dhowells depended upon lookup_one_len() rework; now that prereq is in the mainline, that series had been rebased on top of it and got some exposure and testing..." * 'afs-dh' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: afs: Do better accretion of small writes on newly created content afs: Add stats for data transfer operations afs: Trace protocol errors afs: Locally edit directory data for mkdir/create/unlink/... afs: Adjust the directory XDR structures afs: Split the directory content defs into a header afs: Fix directory handling afs: Split the dynroot stuff out and give it its own ops tables afs: Keep track of invalid-before version for dentry coherency afs: Rearrange status mapping afs: Make it possible to get the data version in readpage afs: Init inode before accessing cache afs: Introduce a statistics proc file afs: Dump bad status record afs: Implement @cell substitution handling afs: Implement @sys substitution handling afs: Prospectively look up extra files when doing a single lookup afs: Don't over-increment the cell usage count when pinning it afs: Fix checker warnings vfs: Remove the const from dir_context::actor
