Håkon Bugge 58aca1f3de RDMA/cm: Base cm_id destruction timeout on CMA values
When a GSI MAD packet is sent on the QP, it will potentially be
retried CMA_MAX_CM_RETRIES times with a timeout value of:

    4.096usec * 2 ^ CMA_CM_RESPONSE_TIMEOUT

The above equates to ~64 seconds using the default CMA values.

The cm_id_priv's refcount will be incremented for this period.
Therefore, the timeout value waiting for a cm_id destruction must be
based on the effective timeout of MAD packets.  To provide additional
leeway, we add 25% to this timeout and use that instead of the
constant 10 seconds timeout, which may result in false negatives.

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.
