Long term, we should work to replace the assert() in libata with
standard kernel WARN_ON().

If someone wanted to handle that conversion, that would be useful. Make
sure to pay attention, the sense of each test must be reversed.

Just so stupid little me understands this:
replace for example:
assert(sg != NULL)
with
WARN_ON(sg == NULL)

right?
...What about WARN_ON being defined bu HAVE_ARCH_BUG_ON and assert by ATA_DEBUG?

Correct.

I would rather just unconditionally use WARN_ON(), and eliminate assert().
