While playing around I found the following three new points: - - Now the length of the subvolume name does not matter. So even the ones with short names are read-only. - - It also happens to a fresh newly created btrfs filesystem. - - If I take a snapshot of an "old" (= writeable) subvolume this is writeable.
I will now reboot into 2.6.37.4, check there, and then report back.
