NAME

6       blk_queue_end_tag - end tag operations for a request
7

SYNOPSIS

9       void blk_queue_end_tag(struct request_queue * q, struct request * rq);
10

ARGUMENTS

12       q
13           the request queue for the device
14
15       rq
16           the request that has completed
17

DESCRIPTION

19       Typically called when end_that_request_first returns 0, meaning all
20       transfers have been done for a request. It's important to call this
21       function before end_that_request_last, as that will put the request
22       back on the free list thus corrupting the internal tag list.
23

NOTES

25       queue lock must be held.
