BLK_UNPREP_REQUEST(9)                     Block Devices                     BLK_UNPREP_REQUEST(9)



NAME
       blk_unprep_request - unprepare a request

SYNOPSIS
       void blk_unprep_request(struct request * req);

ARGUMENTS
       req
           the request

DESCRIPTION
       This function makes a request ready for complete resubmission (or completion). It happens
       only after all error handling is complete, so represents the appropriate moment to
       deallocate any resources that were allocated to the request in the prep_rq_fn. The queue
       lock is held when calling this.
