From 636378535afb837f165beb7de3907896480cf3b2 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 2 Sep 2021 00:38:22 +0100 Subject: io_uring: don't disable kiocb_done() CQE batching Not passing issue_flags from kiocb_done() into __io_complete_rw() means that completion batching for this case is disabled, e.g. for most of buffered reads.
