[PATCH v5 0/6] net/nfb: code cleanup

[Martin Spinler]

> > Patch 2: The new queue iteration still doesn't NULL-check the per-queue pointer before dereferencing. Given the commit message specifically calls out the pointer validity problem, this seems like an oversight.
> > Patch 4: rte_zmalloc_socket for a small control structure of file handles is using limited hugepage memory unnecessarily — plain calloc would suffice.
> 
> Patch 4 raises a good point, file handles are per-process so doesn't need to be in hugepages.

I'll keep that in mind for future changes.

> Not sure about comment about Patch #2. The queues are set to null on close. So there might be small race with another process getting stats.

Oh, I see. The original problem (described in the commit message) has
been solved, but in the case you described, checking for null is still
not enough and some rte_spinlock_lock should also be used.
