Subject: [PATCH 01/12] xfstests: fsstress dump inode info when possible
Date: Thu, 3 Nov 2011 18:24:50 +0400 [thread overview]
Message-ID: <1320330301-2682-2-git-send-email-dmonakhov@openvz.org> (raw)
In-Reply-To: <1320330301-2682-1-git-send-email-dmonakhov@openvz.org>
Fsstress exec behaviour is not completely determinated in case of
low resources mode due to ENOMEM, ENOSPC, etc. In some places we
call stat(2). This information may be halpfull for future
investigations purposes. Let's dump stat info where possible.
