Subject: [PATCH 3/3] pNFS: make _set_lo_fail generic
Date: Sat, 10 Sep 2011 13:41:35 -0400 [thread overview]
Message-ID: <1315676495-3689-4-git-send-email-rees@umich.edu> (raw)
In-Reply-To: <1315676495-3689-1-git-send-email-rees@umich.edu>
From: Peng Tao <bergwolf@gmail.com>
file layout and block layout both use it to set mark layout io failure
bit. So make it generic.
