[ Upstream commite0702d90b7] This function is supposed to return error pointers so it matches the dmz_get_rnd_zone_for_reclaim() function. The current code could lead to a NULL dereference in dmz_do_reclaim() Fixes:b234c6d7a7("dm zoned: improve error handling in reclaim") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Dmitry Fomichev <dmitry.fomichev@wdc.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
