fs/dlm/lock.c:1049:9: sparse: context imbalance in 'dlm_master_lookup' - different lo

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 }

1050
1051 not_found:
1052 error = get_rsb_struct(ls, name, len, &r);

Yes, I just changed the locking there. I've checked it again and it's correct; the kind of lock taken depends on which list the structure was found on.
Thanks
