[PATCH 0/2] drm/i915/gvt: Avoid full proxy f_ops debug attributes

Deepak R Varma <drv@xxxxxxxxx> · Tue, 10 Jan 2023 23:59:12 +0530

This patch series proposes to replace a combination of DEFINE_SIMPLE_ATTRIBUTE() +
debugfs_create_file() by a combination of DEFINE_DEBUGFS_ATTRIBUTE() +
debugfs_create_file_unsafe(). The change reduced overhead in terms of managing
the full proxy f_ops at runtime. The patches 1 & 2 covers for the scan_nonprivbb
 and vgpu_status 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
