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
