'Safe' annotation for block group tree feature missing in output of "mkfs.btrfs -O list-all"

[viktorjk]

The output of mkfs.btrfs -O list-all (btrfs-progs 6.17) shows the annotation (compat=6.1) for the block group tree (bgt) feature. According to the read-the-docs page (stable/latest) the stability of the bgt feature is 'OK'.

Several other features listed in the output have a safe=<kernel version> annotation which corresponds to their stability classification as 'OK' on the read-the-docs page, so it seems the output is missing such an annotation for the bgt feature. Or am I misunderstanding something?

The safe status is added after some time when there are no severe bugs reported, and somebody notices, like you did. I need to go through the commits what would be the good base, probably some recent stable branch, either 6.6 or 6.12.

Updated in devel, safe set to 6.6.
