Subject: [RESEND PATCH v2 0/2] locking/lockdep, drm: apply new lockdep assert in drm_auth.c
Date: Mon, 2 Aug 2021 18:59:55 +0800 [thread overview]
Message-ID: <20210802105957.77692-1-desmondcheongzx@gmail.com> (raw)
Hi all,
My bad for the resend. Adding cc: intel-gfx, and the maintainers and
mailing lists for include/drm/drm_file.h.
Following a discussion on the patch ("drm: use the lookup lock in
drm_is_current_master") [1], Peter Zijlstra proposed new lockdep_assert
helpers to make it convenient to compose lockdep checks together.
This series includes the patch that introduces the new lockdep helpers,
then utilizes these helpers in drm_is_current_master_locked in the
following patch.
v1 -> v2:
Patch 2:
- Updated the kerneldoc on the lock design of drm_file.master to explain
the use of lockdep_assert(). As suggested by Boqun Feng.

Best wishes,
Desmond
