Hello,
Here is a series which adds support for delayed refs. This is needed to enable
later work on adding freespace tree repair code. Additionally, it results in
more code sharing between kernel/user space.
Patches 1-9 are simple prep patches removing some arguments, causing problems
later. They can go independently of the delayed refs work. They don't introduce
any functional changes. Next, patches 10-13 introduce the needed infrastructure
to for delayed refs without actually activating it. Patch 14 finally wires it
up by adding the necessary call outs to btrfs_run_delayed refs and reworking the
extent addition/freeing functions. With all of this done, patch 15 finally
removes the old code.
This series passes all btrfs progs fsck and misc tests + fuzz tests apart from
fuzz-003/007/009 - but those fail without this series so it's unlikely it's
caused by it.
