Subject: [PATCH v4 5/8] virtio/s390: use cacheline aligned airq bit vectors
Date: Thu, 6 Jun 2019 13:51:24 +0200 [thread overview]
Message-ID: <20190606115127.55519-6-pasic@linux.ibm.com> (raw)
In-Reply-To: <20190606115127.55519-1-pasic@linux.ibm.com>
The flag AIRQ_IV_CACHELINE was recently added to airq_iv_create(). Let
us use it! We actually wanted the vector to span a cacheline all along.
