Subject: [PATCH RFC v5 20/21] dept: Disable Dept on struct crypto_larval's completion for now
Date: Wed, 16 Mar 2022 11:26:32 +0900	[thread overview]
Message-ID: <1647397593-16747-21-git-send-email-byungchul.park@lge.com> (raw)
In-Reply-To: <1647397593-16747-1-git-send-email-byungchul.park@lge.com>

struct crypto_larval's completion is used for multiple purposes e.g.
waiting for test to complete or waiting for probe to complete.

The completion variable needs to be split according to what it's used
for. Otherwise, Dept cannot distinguish one from another and doesn't
work properly. Now that it isn't, disable Dept on it.
