From: Horst Hummel Date: Wed, 27 Jul 2005 18:45:02 +0000 (-0700) Subject: [PATCH] s390: fba dasd i/o errors X-Git-Tag: v2.6.13-rc4~25^2~80 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=d61f6f3d8b63a2aadcf8b058fe65581ccd8dee97;p=linux-2.6-omap-h63xx.git [PATCH] s390: fba dasd i/o errors The FBA discipline does not use retries for failed requests. A request fails after the first unsuccessful start attempt. There are some rare conditions (e.g. CIO path recovery) in which the start of an i/o on a fba device can fail. A tiny amount of retries is therefore reasonable.
