blk_queue_end_tag: end tag operations for a request
NAME
blk_queue_end_tag - end tag operations for a request
SYNOPSIS
-
void blk_queue_end_tag(struct request_queue
* q, struct request* rq);
ARGUMENTS
q
-
- the request queue for the device
rq
- the request that has completed
DESCRIPTION
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.
