Merge branch 'work.misc-set_fs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull misc user access cleanups from Al Viro: "The first pile is assorted getting rid of cargo-culted access_ok(), cargo-culted set_fs() and field-by-field copyouts. The same description applies to a lot of stuff in other branches - this is just the stuff that didn't fit into a more specific topical branch" * 'work.misc-set_fs' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: Switch flock copyin/copyout primitives to copy_{from,to}_user() fs/fcntl: return -ESRCH in f_setown when pid/pgid can't be found fs/fcntl: f_setown, avoid undefined behaviour fs/fcntl: f_setown, allow returning error lpfc debugfs: get rid of pointless access_ok() adb: get rid of pointless access_ok() isdn: get rid of pointless access_ok() compat statfs: switch to copy_to_user() fs/locks: don't mess with the address limit in compat_fcntl64 nfsd_readlink(): switch to vfs_get_link() drbd: ->sendpage() never needed set_fs() fs/locks: pass kernel struct flock to fcntl_getlk/setlk fs: locks: Fix some troubles at kernel-doc comments
