From a3669a09536ffcac5296a4ff8d75bdb77c2c0a23 Mon Sep 17 00:00:00 2001 From: Mike Marshall <hubcap@omnibond.com> Date: Fri, 3 May 2019 16:19:19 +0800 Subject: [PATCH] aio: initialize kiocb private in case any filesystems expect it. commit ec51f8ee1e63498e9f521ec0e5a6d04622bb2c67 upstream. A recent optimization had left private uninitialized.
