Hi!
From: Avadhut Naik Avadhut.Naik@amd.com
[ Upstream commit 0706526ec7704dcd046239078ac175d11a88a95e ]
The debugfs_create_blob() function has been used to create read-only binary blobs in debugfs. The function filters out permissions, other than S_IRUSR, S_IRGRP and S_IROTH, provided while creating the blobs.
The very behavior though is being changed through previous patch in the series (fs: debugfs: Add write functionality to debugfs blobs) which makes the binary blobs writable by owners. Thus, all permissions provided while creating the blobs, except S_IRUSR,S_IWUSR, S_IRGRP, S_IROTH, will be filtered by debugfs_create_blob().
This needs previous patch to make sense (according to changelog), and we don't have that. Please drop.
BR, Pavel
