Hi David,

I don't know enough to tell whether this if false alarm. Would you
help confirm it? Thank you.

commit: c04fecb4d9f7753e0cbff7edd03ec68f8721cdce [1/6] dlm: use rsbtbl as resource directory

One new sparse warning is triggered (and there were no old warnings before patch):

+ fs/dlm/lock.c:1049:9: sparse: context imbalance in 'dlm_master_lookup' - different lock contexts for basic block

vim +1049 fs/dlm/lock.c
  1046			unlock_rsb(r);
  1047			put_rsb(r);
  1048		}
> 1049		return 0;
  1050	
  1051	 not_found:
  1052		error = get_rsb_struct(ls, name, len, &r);
