* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse:
  fuse: fix ioctl ABI
  fuse: allow batching of FORGET requests
  fuse: separate queue for FORGET requests
  fuse: ioctl cleanup

Fix up trivial conflict in fs/fuse/inode.c due to RCU lookup having done
the RCU-freeing of the inode in fuse_destroy_inode().
