The test gfp_flag & GFP_NOWAIT was always true, because both GFP_NOIO and GFP_NOWAIT include the flag __GFP_KSWAPD_RECLAIM. Luckily, this oversight didn't result in any harm; the loop always started with "try = 0". This patch removes the faulty test and explicitly starts the loop with "try = 0" (so that we don't hold the mutex in the first iteration). Signed-off-by: Mikulas Patocka <mpatocka@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 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.
