From: Liu Bo Date: Wed, 5 Sep 2018 01:55:27 +0000 (+0800) Subject: Btrfs: remove confusing tracepoint in btrfs_add_reserved_bytes X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6aadd9eb74877a004687a5f70ec20797e5b03c5a;p=openwrt%2Fstaging%2Fblogic.git 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.
