...a migrate will jack up the size for the destination, but leave the size alone for the source, with the idea that you can do a release normally on the source and it all washes out, and then you can do a release again on the destination and it works out right. My way was skipping the release on the trans_block_rsv which still had the jacked up size from our original reservation. So instead release manually from the global reserve if this transaction was using it, and then set the trans->block_rsv back to the trans_block_rsv so that btrfs_end_transaction cleans everything up properly. With this patch xfs...

This is a first draft of a subvolume quota implementation. It is possible to limit subvolumes and any group of subvolumes and also to track the amount of space that will get freed when deleting snapshots. The current version is functionally incomplete, with the main missing feature being the initial scan and rescan of an existing filesystem. I put some effort into writing an introduction into
