Subject: [PATCH] btrfs: sysfs: map sysfs files to their path
Date: Thu, 5 Aug 2021 09:02:46 +0800 [thread overview]
Message-ID: <8a0aac47cbdcc25b7ec861a5d334db1b6add34ae.1628125284.git.anand.jain@oracle.com> (raw)
Sysfs file has grown big. It takes some time to locate the correct
struct attribute to add new files. Create a table and map the
struct attribute to its sysfs path.
Also, fix the comment about the debug sysfs path.
