Did you consider using assert(3)?

Style: extra space after KASSERT.

[dougm]

Remove extra space.

The change from panic to KASSERT was driven entirely by my other mentor. I considered nothing.

What is maxcount ?

334

We ise %jx and uintmax_t for such cases. It is probably fine to cast count to int, but if the value is corrupted, it would hide the information by truncating.

[dougm]

Replace maxcount with count, %llx with %jx, and (long long) with (uintmax_t).

Mark means that you can implement KASSERT using assert(3), he does not suggest to use assert instead of KASSERT.

[dougm]

Use assert() for KASSERT in the blist test program.
