From 7cc5e38f2f0b0b58a22a4c18a56348dd99a71270 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Sun, 12 Feb 2017 17:11:07 +0100 Subject: libceph: osd_request_timeout option osd_request_timeout specifies how many seconds to wait for a response from OSDs before returning -ETIMEDOUT from an OSD request. 0 (default) means no limit. osd_request_timeout is osdkeepalive-precise -- in-flight requests are swept through every osdkeepalive seconds. With ack vs commit behaviour gone, abort_request() is really simple. This is based on a patch from Artur Molchanov .
