The branch, v3-6-test has been updated
       via  c68f4af Remove all uses of "./" in pathnames - make canonical. This will become important when we need to guarantee canonical names for hashing. (cherry picked from commit f278cc1a1f253b6492ef60c2879bdae6a2730084)
       via  4f84d67 Ensure we don't use "./" in findfirst pathnames. Use a directory open of "." instead. (cherry picked from commit de4b09ca01b1747c49bb0058147977ff39d054bb)
       via  f97f6a0 Make processing of incoming stream rename paths common between reply_mv and ntrename. Ensure we don't depend on "./" in the streams module. (cherry picked from commit bb54f72b94dca9206bf377b0d6a4b669e389e339)
      from  fabfc89 s3:smbd: use anonymous_shared_free() for shared memory signing state
