Subject: drbd: Remove some useless paranoia code
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=70dc65e1b3453c5b78ab8ec6bfb604aee7038ae3;p=deliverable%2Flinux.git

drbd: Remove some useless paranoia code

The open_cnt check is an open-coded D_ASSERT() check.

In case the data.work queue is not empty, it does not really help to
know which drbd_work elements remained on that list: they will be freed
immediately afterwards, anyway.
