fcntl: don't cap l_start and l_end values for F_GETLK64 in compat syscall
Currently, we're capping the values too low in the F_GETLK64 case. The fields in that structure are 64-bit values, so we shouldn't need to do any sort of fixup there. Make sure we check that assumption at build time in the future however by ensuring that the sizes we're copying will fit. With this, we no longer need COMPAT_LOFF_T_MAX either, so remove it. Fixes: 94073ad77fff2 (fs/locks: don't mess with the address limit in compat_fcntl64) Reported-by: Vitaly Lipatov <lav@etersoft.ru> Signed-off-by: Jeff Layton <jlayton@redhat.com> Reviewed-by: David Howells <dhowells@redhat.com>
