Subject: Re: [patch] drbd: potential null dereference

Hi Dan, 

Thanks for the work with the static analyzer, but the patch is
bogus. The lc_element_by_index() function causes a BUG_ON before
returning a NULL. The next mail contains a patch that removes
the unnecessary conditional expression operator.

  drbd: lc_element_by_index() never returns NULL
