Looks like it survived all the local beating so far...
Stuff in there: assorted fixes, multilayer overlayfs from Miklos, beginning
of David's series (long-term goal being to have VFS understand stacking
relationships, rather than kludging that up in a bunch of places; for now
it's mostly infrastructure pieces along with some optimizations that could
be standalone). Pushed, please pull from the usual place -

Shortlog:
Al Viro (10):
switch ll_lookup_finish_locks() and ll_revalidate_it_finish() to inode
configfs: configfs_create() init callback is never NULL and it never fails
configfs: fold create_dir() into its only caller
configfs_add_file: fold into its sole caller
don't bother with most of the bad_file_ops methods
hypfs: switch to read_iter/write_iter
Documentation/filesystems/Locking: ->get_sb() is long gone
debugfs: leave freeing a symlink body until inode eviction
procfs: fix race between symlink removals and traversals
autofs4 copy_dev_ioctl(): keep the value of ->size we'd used for allocation
Bastien Nocera (1):
coredump: Fix typo in comment
David Howells (14):
configfs: Fix potential NULL d_inode dereference
Infiniband: Fix potential NULL d_inode dereference
VFS: Introduce inode-getting helpers for layered/unioned fs environments
VFS: Add a whiteout dentry type
VFS: Add a fallthrough flag for marking virtual dentries
VFS: Split DCACHE_FILE_TYPE into regular and special types
Apparmor: mediated_filesystem() should use dentry->d_sb not inode->i_sb
Apparmor: Use d_is_positive/negative() rather than testing dentry->d_inode
TOMOYO: Use d_is_dir() rather than d_inode and S_ISDIR()
Smack: Use d_is_positive() rather than testing dentry->d_inode
SELinux: Use d_is_positive() rather than testing dentry->d_inode
VFS: (Scripted) Convert S_ISLNK/DIR/REG(dentry->d_inode) to d_is_*(dentry)
Cachefiles: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions
fanotify: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions
Kinglong Mee (1):

ovl: dont replace opaque dir
ovl: add mutli-layer infrastructure
ovl: helper to iterate layers
ovl: multi-layer readdir
ovl: multi-layer lookup

ovl: mount: change order of initialization
ovl: improve mount helpers
ovl: make upperdir optional
ovl: support multiple lower layers
