btrfs: zoned: fix mounting with conventional zones

Browse source

[ Upstream commit 6ca64ac276 ]

Since commit 6a921de589 ("btrfs: zoned: introduce
space_info->active_total_bytes"), we're only counting the bytes of a
block group on an active zone as usable for metadata writes. But on a
SMR drive, we don't have active zones and short circuit some of the
logic.

This leads to an error on mount, because we cannot reserve space for
metadata writes.

Fix this by also setting the BLOCK_GROUP_FLAG_ZONE_IS_ACTIVE bit in the
block-group's runtime flag if the zone is a conventional zone.
