From: Dmitry Monakhov Date: Sat, 29 Oct 2011 00:48:10 +0000 (+0400) Subject: xfstests: fsstress dump inode info when possible X-Git-Tag: v2022.05.01~3670 X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=e8f6c8e42e88c631751b09c91a121478f6f63f5c;p=xfstests-dev.git xfstests: fsstress dump inode info when possible 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.
