Merge branch 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull misc vfs updates from Al Viro: - bmap series from cmaiolino - getting rid of convolutions in copy_mount_options() (use a couple of copy_from_user() instead of the __get_user() crap) * 'work.misc' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: saner copy_mount_options() fibmap: Reject negative block numbers fibmap: Use bmap instead of ->bmap method in ioctl_fibmap ecryptfs: drop direct calls to ->bmap cachefiles: drop direct usage of ->bmap method. fs: Enable bmap() function to properly return errors
