Merge tag '6.5-rc-smb3-client-fixes-part1' of git://git.samba.org/sfrench/cifs-2.6

Pull smb client updates from Steve French:

 - Deferred close fix

 - Debugging improvements: display missing mount option, dump rc on
   invalidate inode failures, print client_guid in DebugData, log
   session id when matching session not found in reconnect, new dynamic
   tracepoint for session not found

 - Mount fixes including: potential null dereference, and possible
   memory leak and path name parsing when double slashes

 - Fix potential use after free in compounding

 - Two crediting (flow control) fixes: fix for crediting leak (stress
   scenario with excess lease credits) and better locking around
   updating credits

 - Three cleanups from issues pointed out by the kernel test robot

 - Session state check improvements (including for potential use after
   free)

 - DFS fixes: Fix for getattr on link when DFS disabled, fix for DFS
   mounts to same share with different prefix paths, DFS mount error
   checking improvement
