BLK_QUEUE_END_TAG(9) Block Devices BLK_QUEUE_END_TAG(9)

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.

NOTES queue lock must be held.
