NAME
       blk_queue_end_tag - end tag operations for a request


SYNOPSIS
       void blk_queue_end_tag  (request_queue_t * 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.
