Merge branch 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull more vfs updates from Al Viro: "Assorted stuff from this cycle. The big ones here are multilayer overlayfs from Miklos and beginning of sorting ->d_inode accesses out from David" * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (51 commits) autofs4 copy_dev_ioctl(): keep the value of ->size we'd used for allocation procfs: fix race between symlink removals and traversals debugfs: leave freeing a symlink body until inode eviction Documentation/filesystems/Locking: ->get_sb() is long gone trylock_super(): replacement for grab_super_passive() fanotify: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions Cachefiles: Fix up scripted S_ISDIR/S_ISREG/S_ISLNK conversions VFS: (Scripted) Convert S_ISLNK/DIR/REG(dentry->d_inode) to d_is_*(dentry) SELinux: Use d_is_positive() rather than testing dentry->d_inode Smack: Use d_is_positive() rather than testing dentry->d_inode TOMOYO: Use d_is_dir() rather than d_inode and S_ISDIR() Apparmor: Use d_is_positive/negative() rather than testing dentry->d_inode Apparmor: mediated_filesystem() should use dentry->d_sb not inode->i_sb VFS: Split DCACHE_FILE_TYPE into regular and special types VFS: Add a fallthrough flag for marking virtual dentries VFS: Add a whiteout dentry type VFS: Introduce inode-getting helpers for layered/unioned fs environments Infiniband: Fix potential NULL d_inode dereference posix_acl: fix reference leaks in posix_acl_create autofs4: Wrong format for printing dentry ...
