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

From: Deepak R Varma
Date: Tue Jan 10 2023 - 13:34:49 EST


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
