Hi all, This series adds some testability to the issue fixed by "xfs: reinit btree pointer on attr tree inactivation walk." Patch 1 adds an assert and patch 2 adds an error injection tag to disable buffer LRU caching. I have an xfstests test that reproduces the aforementioned problem reliably using the error injection tag. Note that patch 1 is kind of a cautious attempt to detect the issue. I'm wondering if the better fix is to pass -1 if we indeed should not ever expect to hit a hole in this particular path. Thoughts?
