commit 7ea362427c170061b8822dd41bafaa72b3bcb9ad upstream. If !area->pages statement is true where memory allocation fails, area is freed. In this case 'area->pages = pages' should not executed. So move 'area->pages = pages' after if statement. [akpm@linux-foundation.org: give area->pages the same treatment] Link: http://lkml.kernel.org/r/20190830035716.GA190684@LGEARND20B15 Signed-off-by: Austin Kim <austindh.kim@gmail.com> Acked-by: Michal Hocko <mhocko@suse.com> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Cc: Uladzislau Rezki (Sony) <urezki@gmail.com> Cc: Roman Gushchin <guro@fb.com> Cc: Roman Penyaev <rpenyaev@suse.de> Cc: Rick Edgecombe <rick.p.edgecombe@intel.com> Cc: Mike Rapoport <rppt@linux.ibm.com> Cc: Andrey Ryabinin <aryabinin@virtuozzo.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
