Merge tag 'locks-v4.5-1' of git://git.samba.org/jlayton/linux
Pull file locking updates from Jeff Layton:
"File locking related changes for v4.5 (pile #1)
Highlights:
- new Kconfig option to allow disabling mandatory locking (which is
racy anyway)
- new tracepoints for setlk and close codepaths
- fix for a long-standing bug in code that handles races between
setting a POSIX lock and close()"
