Subject: [PATCH v2 net-next 0/2] tcp: reduce cpu usage when SO_SNDBUF is set
Date: Wed, 22 Jun 2016 11:32:49 -0400	[thread overview]
Message-ID: <cover.1466608332.git.jbaron@akamai.com> (raw)

Hi,

I've added a patch to upgrade smp_mb__after_atomic() to a smp_mb()
as Eric Dumazet pointed out. Also combined the clearing of
SOCK_SHORT_WRITE with SOCK_QUEUE_SHRUNK.

Thanks,

-Jason

v2:
-upgrade smp_mb__after_atomic to smp_mb() in tcp_poll()
-combine clear of SOCK_SHORT_WRITE with SOCK_QUEUE_SHRUNK
