When kmem_cache_alloc in function lc_create returns null, we will free the memory already allocated. The loop of kmem_cache_free is wrong, especially: i = 0 ==> do wrong loop i > 0 ==> do not free element[0] Link: https://lkml.kernel.org/r/20220618082521.7082-1-wuchi.zero@gmail.com Signed-off-by: wuchi <wuchi.zero@gmail.com> Cc: Philipp Reisner <philipp.reisner@linbit.com> Cc: Lars Ellenberg <lars.ellenberg@linbit.com> Cc: Christoph Bhmwalder <christoph.boehmwalder@linbit.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.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.
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.
