    block: add blk_rq_set_block_pc() · f27b087b
    Jens Axboe authored
    With the optimizations around not clearing the full request at alloc
    time, we are leaving some of the needed init for REQ_TYPE_BLOCK_PC
    up to the user allocating the request.
    
    Add a blk_rq_set_block_pc() that sets the command type to
    REQ_TYPE_BLOCK_PC, and properly initializes the members associated
    with this type of request. Update callers to use this function instead
    of manipulating rq->cmd_type directly.
    
    Includes fixes from Christoph Hellwig <hch@lst.de> for my half-assed
    attempt.
