mtip32xx: use runtime tag to initialize command header
mtip32xx supposes that 'request_idx' passed to .init_request() is tag of the request, and use that as request's tag to initialize command header. After MQ IO scheduler is in, request tag assigned isn't same with the request index anymore, so cause strange hardware failure on mtip32xx, even whole system panic is triggered. This patch fixes the issue by initializing command header via request's real tag. Signed-off-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>
