Steve French e8eeca0bf4 smb3: do not reserve too many oplock credits
There were cases reported where servers will sometimes return more
credits than requested on oplock break responses, which can lead to
most of the credits being allocated for oplock breaks (instead of
for normal operations like read and write) if number of SMB3 requests
in flight always stays above 0 (the oplock and echo credits are
rebalanced when in flight requests goes down to zero).

If oplock credits gets unexpectedly large (e.g. three is more than it
would ever be expected to be) and in flight requests are greater than
zero, then rebalance the oplock credits and regular credits (go
back to reserving just one oplock credit).

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.
