Subject: block: dump request state on seeing a corrupted request completion
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8182924bc5850281985d73c312876746acd390b5;p=mv-sheeva.git

block: dump request state on seeing a corrupted request completion

Currently we just dump a non-informative 'request botched' message.
Lets actually try and print something sane to help debug issues
around this.
