Here is the full test case:
TEST(LibCephFS, MountRootChdir) {
struct ceph_mount_info *cmount;
/* create mount and new directory */
ASSERT_EQ(ceph_create(&cmount, NULL), 0);
ASSERT_EQ(ceph_conf_read_file(cmount, NULL), 0);
ASSERT_EQ(ceph_mount(cmount, "/"), 0);
ASSERT_EQ(ceph_mkdir(cmount, "/xyz", 0700), 0);
ceph_shutdown(cmount);
/* create mount with non-"/" root */
ASSERT_EQ(ceph_create(&cmount, NULL), 0);
ASSERT_EQ(ceph_conf_read_file(cmount, NULL), 0);
ASSERT_EQ(ceph_mount(cmount, "/xyz"), 0);
/* should be at "root" directory, but blows up */
ASSERT_STREQ(ceph_getcwd(cmount), "/");
}
