When a SMB connection is reset and reconnected, the negotiated IO parameters (rsize/wsize) can become out of sync with the server's current capabilities. This can lead to suboptimal performance or even IO failures if the server's limits have changed. This patch implements automatic IO size renegotiation: 1. Adds cifs_renegotiate_iosize() function to update all superblocks associated with a tree connection 2. Updates each mount's rsize/wsize based on current server capabilities 3. Calls this function after successful tree connection reconnection With this change, all mount points will automatically maintain optimal and reliable IO parameters after network disruptions, using the bidirectional mapping added in previous patches. This completes the series improving connection resilience by keeping mount parameters synchronized with server capabilities.

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 reStructuredText 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.
