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 DRRS and FBC f_ops debugfs attributes respectively.
