Merge tag 'locks-v3.16' of git://git.samba.org/jlayton/linux into next
Pull file locking changes from Jeff Layton: "Pretty quiet on the file-locking related front this cycle. Just some small cleanups and the addition of some tracepoints in the lease handling code" * tag 'locks-v3.16' of git://git.samba.org/jlayton/linux: locks: add some tracepoints in the lease handling code fs/locks.c: replace seq_printf by seq_puts locks: ensure that fl_owner is always initialized properly in flock and lease codepaths
