b. Are there better ways (walking the tree using
BTRFS_IOC_TREE_SEARCH?) to accomplish this than using/proc/self/mountinfo?Not yet, but I'm definitely open to adding them. Lets just hash out what you need and we'll either go through Kay's stuff or add ioctls for you.
Chris, what about adding a /sys/btrfs/<fs-uuid>/<subvol-id> interface ?
For example under
/sys/btrfs/<fs-uuid>
we can list the devices which btrfs uses
under
/sys/btrfs/<fs-uuid>/<subvol-id>
we can show/set the subvolume properties (like RO, compres....)
