[PATCH 0/2] btrfs: add a delayed ref self test

[Josef Bacik <josef@toxicpanda.com>]

Hello,

I made a silly mistake when refactoring the delayed ref code to make it easier
to understand, and that resulted in a whole lot of not fun trying to find what
went wrong with boxes started falling over when we were deploying 6.11.  This
style of bug is easy to catch with basic unit testing, so add a variety of unit
tests for delayed refs to make sure I don't break things again.  One patch moves
an important helper and exports it so that we can do the testing, the other
patch is a giant patch of all the tests with a few changes that are necessary to
make everything work.  I validated these work properly and catch a variety of
bugs that I hand introduced to the delayed ref code.  Thanks,
