From ef4859d6479d19bcc65c3156cf3b7dd747355c29 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Mon, 1 Apr 2013 18:58:26 -0500 Subject: libceph: define ceph_decode_pgid() only once There are two basically identical definitions of __decode_pgid() in libceph, one in "net/ceph/osdmap.c" and the other in "net/ceph/osd_client.c". Get rid of both, and instead define a single inline version in "include/linux/ceph/osdmap.h".
