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.
Also fixes a bug that was:

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
