AIO is not safe, SMP or not.
Are you maybe confusion AIO (a POSIX mandated API) with
async mounts?

AIO works fine, I think, and is happy with SMP.

Can you point to some specific PRs about this or crashdumps before
(or at least while) taking pot shots at the AIO implementation?

In the mean time, until somebody can substantiate that claim... is AIO SMP
safe?
Quick question(s):
1. Is AIO SMP-safe?
2. If not, how could one force coherency? (Read and rewrite locked
a word from each cache line?) Is it worth the effort, or should
