X-Git-Tag: v2.6.25-rc1~1172^2~10
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ea6f06f416347448645e60294d92c0c19aba8589;p=pandora-kernel.git

blk_end_request: changing cpqarray (take 4)

This patch converts cpqarray to use blk_end_request interfaces.
Related 'ok' arguments are converted to 'error'.

cpqarray is a little bit different from "normal" drivers.
cpqarray directly calls bio_endio() and disk_stat_add()
when completing request.  But those can be replaced with
__end_that_request_first().
After the replacement, request completion procedures of
those drivers become like the following:
    o end_that_request_first()
    o add_disk_randomness()
    o end_that_request_last()
This can be converted to __blk_end_request() by following
the rule (b) mentioned in the patch subject
"[PATCH 01/30] blk_end_request: add new request completion interface".
