Subject: [PATCH v3 18/25] block/coroutines: I/O API
Date: Tue, 12 Oct 2021 04:48:59 -0400 [thread overview]
Message-ID: <20211012084906.2060507-19-eesposit@redhat.com> (raw)
In-Reply-To: <20211012084906.2060507-1-eesposit@redhat.com>
block coroutines functions run in different aiocontext, and are
not protected by the BQL. Therefore are I/O.
