Is the first hunk right ?

xfs_da_node_lookup_int called as

         error = xfs_da_node_lookup_int(state,&rval);

and returns with

         *result = retval;

so, on return, error == 0 and rval == an error code. The next lines:

         if (error)
                 rval = error;

won't change that. But previously if rval != EEXIST you returned rval.
With the change below, you return error, which is zero.


Thanks, guilty as charged. need to add the error = EEXIST.
