The change reduced overhead in terms of managing the full proxy f_ops at runtime. The patches 1 & 2 covers for the DRRS and FBC f_ops debugfs attributes respectively. Following coccicheck make command helped identify this change: make coccicheck M=drivers/gpu/drm/i915/ MODE=patch COCCI=./scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci Changes in v2: - Individual patches clubbed in patch set - Update patch log message to include coccicheck make command Deepak R Varma (2): drm/i915/display: Avoid full proxy f_ops for DRRS debug attributes drm/i915/fbc: Avoid full proxy f_ops for FBC debug attributes drivers/gpu/drm/i915/display/intel_drrs.c | 8 ++++---- drivers/gpu/drm/i915/display/intel_fbc.c | 12 ++++++------ 2 files changed, 10 insertions(+), 10 deletions(-)
