From 6aadd9eb74877a004687a5f70ec20797e5b03c5a Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Wed, 5 Sep 2018 09:55:27 +0800 Subject: [PATCH] Btrfs: remove confusing tracepoint in btrfs_add_reserved_bytes Here we're not releasing any space, but transferring bytes from ->bytes_may_use to ->bytes_reserved. The last change to the code in commit 18513091af9483ba8 ("btrfs: update btrfs_space_info's bytes_may_use timely") removed a conditional tracepoint and the logic changed too but the tracepiont remained.
