NAME
blk_queue_end_tag - end tag operations for a requestSYNOPSIS
- 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.
NOTES
queue lock must be held.
