Subject: [PATCH 06/10] pnfsblock: init pg_bsize properly
Date: Thu, 22 Sep 2011 21:50:13 -0400 [thread overview]
Message-ID: <1316742617-14766-7-git-send-email-rees@umich.edu> (raw)
In-Reply-To: <1316742617-14766-1-git-send-email-rees@umich.edu>
From: Peng Tao <bergwolf@gmail.com>
pg_bsize is server->wsize/rsize by default. We would want to use the lseg
length.
