Can we please just ensure ASSERT always evaluates the argument,
similar to BUG()?

This and the hunk below will break the CONFIG_XFS_WARN build.

Assuming you meant BUG_ON or something that actually takes a parameter,
yes you can do that, though now we have to fix up a bunch of things like
the xfs_trans debug counter asserts and anything that asserts on
xfs_isilocked.

-.text                         785555      0
+.text                         787843      0

I guess that's only 0.29% larger...

This one ought to be fine, because the ASSERT is itself protected by an
'#ifdef DEBUG'.

That looks like a different assert from the one that uses last_lsn..?
