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.
