[PATCH 0/2] xfs: test support for xattr inactivate

[Brian Foster <bfoster@redhat.com>]

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?

Brian
