Subject: [PATCH 0/2] use DEFINE_DEBUGFS_ATTRIBUTE instead of DEFINE_SIMPLE_ATTRIBUTE
Date: Sat, 28 Mar 2020 12:04:53 +0530 [thread overview]
Message-ID: <20200328063456.24012-1-rohitsarkar5398@gmail.com> (raw)
The debugfs_create_file_unsafe method does not protect the fops given to
it from file removal. It must be used with DEFINE_DEBUGFS_ATTRIBUTE
which makes the fops aware of the file lifetime.
Further using DEFINE_DEBUGFS_ATTRIBUTE along with
debugfs_create_file_unsafe significantly reduces the overhead introduced by
debugfs_create_file which creates a lifetime managing proxy around each
fops handed in. Refer [1] for more on this.
Fixes the following warnings reported by coccinelle:
drivers/iio/imu//adis16460.c:126:0-23: WARNING: adis16460_flash_count_fops should be defined with DEFINE_DEBUGFS_ATTRIBUTE
