Merge branch 'work.dcache2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull dcache and mountpoint updates from Al Viro: "Saner handling of refcounts to mountpoints. Transfer the counting reference from struct mount ->mnt_mountpoint over to struct mountpoint ->m_dentry. That allows us to get rid of the convoluted games with ordering of mount shutdowns. The cost is in teaching shrink_dcache_{parent,for_umount} to cope with mixed-filesystem shrink lists, which we'll also need for the Slab Movable Objects patchset" * 'work.dcache2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: switch the remnants of releasing the mountpoint away from fs_pin get rid of detach_mnt() make struct mountpoint bear the dentry reference to mountpoint, not struct mount Teach shrink_dcache_parent() to cope with mixed-filesystem shrink lists fs/namespace.c: shift put_mountpoint() to callers of unhash_mnt() __detach_mounts(): lookup_mountpoint() can't return ERR_PTR() anymore nfs: dget_parent() never returns NULL ceph: don't open-code the check for dead lockref
