[LU-15038] mgc_fs_setup() can leak cl_mgc_mutex reference

Duplicate — Fri, 22 Oct 2021 16:47:00 +0000

It is possible for mgc_fs_setup() to leak a reference to cl_mgc_mutex if local_oid_storage_init() fails:

        /* The mgc fs exclusion mutex. Only one fs can be setup at a time. */
        mutex_lock(&cli->cl_mgc_mutex); 
        
        /* Setup the configs dir */
        fid.f_seq = FID_SEQ_LOCAL_NAME;
        fid.f_oid = 1;
        fid.f_ver = 0;
        rc = local_oid_storage_init(env, lsi->lsi_dt_dev, &fid,
                                    &cli->cl_mgc_los);
        if (rc)
                RETURN(rc);
