Christoph Hellwig 5948705adb xfs: don't allocate the xfs_extent_busy structure for zoned RTGs ... Busy extent tracking is primarily used to ensure that freed blocks are not reused for data allocations before the transaction that deleted them has been committed to stable storage, and secondarily to drive online discard. None of the use cases applies to zoned RTGs, as the zoned allocator can't overwrite blocks before resetting the zone, which already flushes out all transactions touching the RTGs. So the busy extent tracking is not needed for zoned RTGs, and also not called for zoned RTGs. But somehow the code to skip allocating and freeing the structure got lost during the zoned XFS upstreaming process. This not only causes these structures to unnecessarily allocated, but can also lead to memory leaks as the xg_busy_extents pointer in the xfs_group structure is overlayed with the pointer for the linked list of to be reset zones. Stop allocating and freeing the structure to not pointlessly allocate memory which is then leaked when the zone is reset.
