      Pull iov_iter updates from Al Viro:
       "More iov_iter work - missing counterpart of iov_iter_init() for
        bvec-backed ones and vfs_read_iter()/vfs_write_iter() - wrappers for

      Merge branch 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs · c6b1de1b
      Linus Torvalds authored
      Pull debugfs patches from Al Viro:
       "debugfs patches, mostly to make it possible for something like tracefs
        to be transparently automounted on given directory in debugfs.
      
        New primitive in there is debugfs_create_automount(name, parent, func,
        arg), which creates a directory and makes its ->d_automount() return
        func(arg).  Another missing primitive was debugfs_create_file_size() -
        open-coded in quite a few places.  Dave's patch adds it and converts
        the open-code instances to calling it"
      
      * 'debugfs_automount' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
        debugfs: Provide a file creation function that also takes an initial size
        new primitive: debugfs_create_automount()
        debugfs: split end_creating() into success and failure cases
        debugfs: take mode-dependent parts of debugfs_get_inode() into callers
        fold debugfs_mknod() into callers
        fold debugfs_create() into caller
        fold debugfs_mkdir() into caller
        debugfs_mknod(): get rid useless arguments
        fold debugfs_link() into caller
        debugfs: kill __create_file()
        debugfs: split the beginning and the end of __create_file() off
        debugfs_{mkdir,create,link}(): get rid of redundant argument

      Pull misc VFS updates from Al Viro:
       "This cycle a lot of stuff sits on topical branches, so I'll be sending
        more or less one pull request per branch.
      
        This is the first pile; more to follow in a few.  In this one are
        several misc commits from early in the cycle (before I went for
        separate branches), plus the rework of mntput/dput ordering on umount,
        switching to use of fs_pin instead of convoluted games in
        namespace_unlock()"
      
      * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
        switch the IO-triggering parts of umount to fs_pin
        new fs_pin killing logics

        get rid of the second argument of acct_kill()
        take count and rcu_head out of fs_pin
        dcache: let the dentry count go down to zero without taking d_lock

      seccomp: cap SECCOMP_RET_ERRNO data to MAX_ERRNO · 580c57f1
      Kees Cook authored
      
      
      The value resulting from the SECCOMP_RET_DATA mask could exceed MAX_ERRNO
      when setting errno during a SECCOMP_RET_ERRNO filter action.  This makes
      sure we have a reliable value being set, so that an invalid errno will not
      be ignored by userspace.

      Call __set_current_state() instead of assigning the new state directly.
      These interfaces also aid CONFIG_DEBUG_ATOMIC_SLEEP environments, keeping
      track of who changed the state.
