blk_queue_end_tag - end tag operations for a request
void blk_queue_end_tag (request_queue_t * q, struct request * rq);
q the request queue for the device
rq the request that has completed
Typically called when end_that_request_first returns 0, meaning all
transfers have been done for a request. It’s important to call this
function before end_that_request_last, as that will put the request
back on the free list thus corrupting the internal tag list.
queue lock must be held.
