In analyzing problems, one missing piece of debug data is when the mount occurred. A related problem is when collecting stats we don't know the period of time the stats covered, ie when this set of stats for the tcon started to be collected. To make debugging easier track the stats begin time. Set it when the mount occurred at mount time, and reset it to current time whenever stats are reset. For example, ... 1) \\localhost\test SMBs: 14 since 2024-01-17 22:17:30 UTC Bytes read: 0 Bytes written: 0 Open files: 0 total (local), 0 open on server TreeConnects: 1 total 0 failed TreeDisconnects: 0 total 0 failed ... 2) \\localhost\scratch SMBs: 24 since 2024-01-17 22:16:04 UTC Bytes read: 0 Bytes written: 0 Open files: 0 total (local), 0 open on server TreeConnects: 1 total 0 failed TreeDisconnects: 0 total 0 failed ... Note the time "since ... UTC" is now displayed in /proc/fs/cifs/Stats for each share that is mounted.

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.
