The reason is simple, for my convenience I've added the user to the 'disk' group so I can access the block devices without root. This patch stops to read the block devs directly and uses the ioctl BTRFS_IOC_FS_INFO which gives me a silent EPERM.

Ah. good catch. but what do you suggest. ? as of now user on disk-group is able to do things like, check --repair. but won't be able to list the subvol / manage the snapshots, and is able to run btrfs fi show -d but won't be able to run btrfs fi show / -m. what do we do in this case ? OR when /sys interface is ready that should help to manage based on the user-groups.?
