Linux kernel source tree
96feb73def
When authenc is invoked with MAY_BACKLOG, it needs to pass EINPROGRESS
notifications back up to the caller when the underlying algorithm
returns EBUSY synchronously.
However, if the EBUSY comes from the second part of an authenc call,
i.e., it is asynchronous, both the EBUSY and the subsequent EINPROGRESS
notification must not be passed to the caller.
Implement this by passing a mask to the function that starts the
second half of authenc and using it to determine whether EBUSY
and EINPROGRESS should be passed to the caller.
This was a deficiency in the original implementation of authenc
because it was not expected to be used with MAY_BACKLOG.

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.
