Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs pile 1 from Al Viro: "Unfortunately, this merge window it'll have a be a lot of small piles - my fault, actually, for not keeping #for-next in anything that would resemble a sane shape ;-/ This pile: assorted fixes (the first 3 are -stable fodder, IMO) and cleanups + %pd/%pD formats (dentry/file pathname, up to 4 last components) + several long-standing patches from various folks. There definitely will be a lot more (starting with Miklos' check_submount_and_drop() series)" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (26 commits) direct-io: Handle O_(D)SYNC AIO direct-io: Implement generic deferred AIO completions add formats for dentry/file pathnames kvm eventfd: switch to fdget powerpc kvm: use fdget switch fchmod() to fdget switch epoll_ctl() to fdget switch copy_module_from_fd() to fdget git simplify nilfs check for busy subtree ibmasmfs: don't bother passing superblock when not needed don't pass superblock to hypfs_{mkdir,create*} don't pass superblock to hypfs_diag_create_files don't pass superblock to hypfs_vm_create_files() oprofile: get rid of pointless forward declarations of struct super_block oprofilefs_create_...() do not need superblock argument oprofilefs_mkdir() doesn't need superblock argument don't bother with passing superblock to oprofile_create_stats_files() oprofile: don't bother with passing superblock to ->create_files() don't bother passing sb to oprofile_create_files() coh901318: don't open-code simple_read_from_buffer() ...
