From d178a9e74006e80f568d87e29f2a68f14fc7cbb1 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Tue, 13 Nov 2012 21:11:15 -0600 Subject: [PATCH] libceph: don't set flags in ceph_osdc_alloc_request() The only thing ceph_osdc_alloc_request() really does with the flags value it is passed is assign it to the newly-created osd request structure. Do that in the caller instead. Both callers subsequently call ceph_osdc_build_request(), so have that function (instead of ceph_osdc_alloc_request()) issue a warning if a request comes through with neither the read nor write flags set.
