From b7ec35b304b64af2830027350cc99d31e6e537c2 Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Thu, 28 Apr 2016 16:07:25 +0200 Subject: [PATCH] libceph: change ceph_osdmap_flag() to take osdc For the benefit of every single caller, take osdc instead of map. Also, now that osdc->osdmap can't ever be NULL, drop the check.
