Restructure the function to better separate the locked and the unlocked parts. Use the "old_req" local variable to mean only the queued request, and not any auxiliary requests added onto its misc.write.next list. These changes are in preparation for the following patch. Also turn BUG_ON instances into WARN_ON and add a header comment explaining what the function does. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
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.
