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()
