  CIFS: fix POSIX lock leak and invalid ptr deref (2019-03-14 19:32:36 -0500)

----------------------------------------------------------------
- Various additional dynamic tracing tracepoints
- Debugging improvements (including ability to query the server via
SMB3 fsctl from userspace tools which can help with stats and
debugging)
- One minor performance improvement (root directory inode caching)
- Crediting (SMB3 flow control) fixes
- Some cleanup (docs and to mknod)
- Important fixes: one to smb3 implementation of fallocate zero range
(which fixes three xfstests) and a POSIX lock fix
----------------------------------------------------------------
