From: Håkon Bugge Date: Tue, 8 Aug 2017 09:13:32 +0000 (+0200) Subject: rds: Reintroduce statistics counting X-Git-Tag: v4.14-rc1~314^2~3 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=05bfd7dbb53a10be4a3e7aebaeec04b558198d49;p=platform%2Fkernel%2Flinux-rpi.git rds: Reintroduce statistics counting In commit 7e3f2952eeb1 ("rds: don't let RDS shutdown a connection while senders are present"), refilling the receive queue was removed from rds_ib_recv(), along with the increment of s_ib_rx_refill_from_thread. Commit 73ce4317bf98 ("RDS: make sure we post recv buffers") re-introduces filling the receive queue from rds_ib_recv(), but does not add the statistics counter. rds_ib_recv() was later renamed to rds_ib_recv_path(). This commit reintroduces the statistics counting of s_ib_rx_refill_from_thread and s_ib_rx_refill_from_cq.
