From fdf59eb548e51bce81382c39f1a5fd4cb9403b78 Mon Sep 17 00:00:00 2001 From: Steve French Date: Sun, 27 Mar 2022 16:07:30 -0500 Subject: smb3: cleanup and clarify status of tree connections Currently the way the tid (tree connection) status is tracked is confusing. The same enum is used for structs cifs_tcon and cifs_ses and TCP_Server_info, but each of these three has different states that they transition among. The current code also unnecessarily uses camelCase. Convert from use of statusEnum to a new tid_status_enum for tree connections. The valid states for a tid are: TID_NEW = 0, TID_GOOD, TID_EXITING, TID_NEED_RECON, TID_NEED_TCON, TID_IN_TCON, TID_NEED_FILES_INVALIDATE, /* unused, considering removing in future */ TID_IN_FILES_INVALIDATE It also removes CifsNeedTcon, CifsInTcon, CifsNeedFilesInvalidate and CifsInFilesInvalidate from the statusEnum used for session and TCP_Server_Info since they are not relevant for those. A follow on patch will fix the places where we use the tcon->need_reconnect flag to be more consistent with the tid->status.
