Naohiro Aota 1ada69f61c btrfs: zoned: unset dedicated block group on allocation failure ... Allocating an extent from a block group can fail for various reasons. When an allocation from a dedicated block group (for tree-log or relocation data) fails, we need to unregister it as a dedicated one so that we can allocate a new block group for the dedicated one. However, we are returning early when the block group in case it is read-only, fully used, or not be able to activate the zone. As a result, we keep the non-usable block group as a dedicated one, leading to further allocation failure. With many block groups, the allocator will iterate hopeless loop to find a free extent, results in a hung task. Fix the issue by delaying the return and doing the proper cleanups.
