This is step 1/4 of a patch series to fix mid_q_entry memory leaks caused by race conditions in callback execution. The current mid_lock name is somewhat ambiguous about what it protects. To prepare for splitting this lock into separate, more granular locks, this patch renames mid_lock to mid_queue_lock to clearly indicate its specific responsibility for protecting the pending_mid_q list and related queue operations. No functional changes are made in this patch - it only prepares the codebase for the lock splitting that follows. - mid_queue_lock for queue operations - mid_counter_lock for mid counter operations - per-mid locks for individual mid state management Signed-off-by: Wang Zhaolong <wangzhaolong@huaweicloud.com> Acked-by: Enzo Matsumiya <ematsumiya@suse.de> Signed-off-by: Steve French <stfrench@microsoft.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.
