Subject: [Question] drivers/infiniband: on smp_read_barrier_depends() usages
Date: Wed, 11 Oct 2017 19:42:39 +0200 [thread overview]
Message-ID: <20171011174239.GA3224@andrea> (raw)
Dear IB supporters,
I was reviewing current usages of smp_read_barrier_depends()
https://marc.info/?l=linux-kernel&m=150723193717856&w=2
when I stubled over drivers/infiniband/: I've found 19 instances of this
barrier here, but their intent is unclear to me and I'm wondering if you
could clarify it. (Most of these usages are accompanied by the comment
/* see post_one_send() */
suggesting that they're sharing a common intent.)
Thanks in advance,
Andrea
