From d2e4634504768d287f5d68ae45ca5995177aea1c Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Tue, 20 Oct 2009 11:33:12 +0200 Subject: [PATCH] raw/linux-aio: Also initialize POSIX AIO When using Linux AIO raw still falls back to POSIX AIO sometimes, so we should initialize it. Not initializing it happens to work if POSIX AIO is used by another drive, or if the format is not specified (probing the format uses POSIX AIO) or by pure luck (e.g. it doesn't seem to happen any more with qcow2 since we have re-added synchronous qcow2 functions).
