ide: another possible ide panic fix for blk-end-request
I have reviewed all blk-end-request patches again to confirm whether
there are any similar problems with the last week's ide-cd panic:
http://lkml.org/lkml/2008/1/29/140
And I found a possible similar bug in ide-io change:
ide_end_drive_cmd() could be called for blk_pc_request() which could
have bios. To complete such requests correctly, we need to pass
the actual size of the request.
Otherwise, __blk_end_request() returns 1 because the request still has
bios, and the system will BUG() unnecessarily.
The following patch fixes the bug and should be applied on top of
Linus' git.
