Subject: [LTP] [POSIX][PATCH 1/2]Use aio_error instead signal hander at aio_suspend/1-1
Date: Thu, 11 Nov 2010 11:17:13 +0800	[thread overview]
Message-ID: <4CDB6039.2050200@cn.fujitsu.com> (raw)
In-Reply-To: <4CDB5E53.6070604@cn.fujitsu.com>

aio_suspend may be interrupted by IO request's completion signal, so we
should use aio_error instead signal hander to check whether this request
has complete.
