parentcifs: fix mode bits from dir listing when mounted with modefromsid (diff)
smb3: add one more dynamic tracepoint missing from strict fsync path
We didn't have a dynamic trace point for catching errors in file_write_and_wait_range error cases in cifs_strict_fsync. Since not all apps check for write behind errors, it can be important for debugging to be able to trace these error paths.
