Naohiro Aota 760e69c4c2 btrfs: zoned: activate block group only for extent allocation ... In btrfs_make_block_group(), we activate the allocated block group, expecting that the block group is soon used for allocation. However, the chunk allocation from flush_space() context broke the assumption. There can be a large time gap between the chunk allocation time and the extent allocation time from the chunk. Activating the empty block groups pre-allocated from flush_space() context can exhaust the active zone counter of a device. Once we use all the active zone counts for empty pre-allocated block groups, we cannot activate new block group for the other things: metadata, tree-log, or data relocation block group. That failure results in a fake -ENOSPC. This patch introduces CHUNK_ALLOC_FORCE_FOR_EXTENT to distinguish the chunk allocation from find_free_extent(). Now, the new block group is activated only in that context.
