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¶
struct request_queue * q
the request queue for the device
struct request * 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.
