Description

From Noah.
If Ceph is mounted with a non-existent directory, the mount call returns a success, but on unmount does this:

Was the error code from ceph_mount() getting checked? I'm not able to reproduce this with either fuse or the following test:

struct ceph_mount_info *cmount;
ASSERT_EQ(0, ceph_create(&cmount, NULL));
  ASSERT_EQ(0, ceph_conf_read_file(cmount, NULL));
  ASSERT_NE(0, ceph_mount(cmount, "/non-exist"));

As of last week, I cannot reproduce either, but I didn't look for a specific commit that fixed it.
