  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
----------------------------------------------------------------
Aurelien Aptel (2):
      CIFS: make mknod() an smb_version_op
      CIFS: fix POSIX lock leak and invalid ptr deref

Ronnie Sahlberg (11):
      cifs: change wait_for_free_request() to take flags as argument
      cifs: pass flags down into wait_for_free_credits()
      cifs: wait_for_free_credits() make it possible to wait for >=1 credits
      cifs: prevent starvation in wait_for_free_credits for
multi-credit requests
      cifs: add a timeout argument to wait_for_free_credits
      cifs: simplify how we handle credits in compound_send_recv()
      cifs: cache FILE_ALL_INFO for the shared root handle
      cifs: add SMB2_ioctl_init/free helpers to be used with compounding
      cifs: fix smb3_zero_range so it can expand the file-size when required
      cifs: fix incorrect handling of smb2_set_sparse() return in
smb3_simple_falloc
      SMB3: Allow SMB3 FSCTL queries to be sent to server from tools

Steve French (9):
      smb3: display security information in /proc/fs/cifs/DebugData
more accurately
      smb3: add dynamic tracepoint for timeout waiting for credits
      smb3: display volume serial number for shares in /proc/fs/cifs/DebugData
      smb3: Add dynamic trace points for various compounded smb3 ops
      smb3: add dynamic tracepoints for simple fallocate and zero range
      SMB3: passthru query info doesn't check for SMB3 FSCTL passthru
      cifs: remove unused value pointed out by Coverity
      cifs: minor documentation updates
      smb2: fix typo in definition of a few error flags
