Subject: [PATCH 0/4] panfrost: Locking fixes
Date: Mon, 19 Aug 2019 11:12:00 -0500 [thread overview]
Message-ID: <20190819161204.3106-1-robh@kernel.org> (raw)
With further testing of recent changes with lockdep and other locking
checks enabled, we've found several bugs in the shrinker code and one
sleep while atomic in panfrost_gem_open(). This series addresses those
issues.
