blk_queue_end_tag (9) Linux Manual Page
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.
Notes
queue lock must be held.
