Cocci is confused by the try lock then release RCU and return logic here. So separate the try lock part out into a standalone helper. The code is easier to follow too. No feature change, fixes: cocci warnings: (new ones prefixed by >>) >> mm/list_lru.c:82:3-9: preceding lock on line 77 >> mm/list_lru.c:82:3-9: preceding lock on line 77 mm/list_lru.c:82:3-9: preceding lock on line 75 mm/list_lru.c:82:3-9: preceding lock on line 75 Link: https://lkml.kernel.org/r/20250526180638.14609-1-ryncsn@gmail.com Signed-off-by: Kairui Song <kasong@tencent.com> Reported-by: kernel test robot <lkp@intel.com> Reported-by: Julia Lawall <julia.lawall@inria.fr> Closes: https://lore.kernel.org/r/202505252043.pbT1tBHJ-lkp@intel.com/ Reviewed-by: Qi Zheng <zhengqi.arch@bytedance.com> Reviewed-by: Muchun Song <muchun.song@linux.dev> Reviewed-by: SeongJae Park <sj@kernel.org> Cc: Chengming Zhou <zhouchengming@bytedance.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Kairui Song <kasong@tencent.com> Cc: Roman Gushchin <roman.gushchin@linux.dev> 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 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.
