Subject: [Qemu-devel] [PATCH] improved patch from block-raw-posix.c
Date: Sun, 21 Jun 2009 19:55:43 -0400 [thread overview]
Message-ID: <d097564c372451488331f3a8514b8da1@gmail.com> (raw)
This patch is an improvement over a previous patch for the file
block-raw-posix.c. This time the code checks to see if O_FSYNC is
defined before defining O_SYNC as O_FSYNC. If it isn't defined, then it
defines O_SYNC as 0.
