    block: fix an address space warning in blk-map.c · 14417799
    Namhyung Kim authored
    Change type of 2nd parameter of blk_rq_aligned() into unsigned long
    and remove unnecessary casting. Now we can call it with 'uaddr'
    instead of 'ubuf' in __blk_rq_map_user() so that it can remove
    following warnings from sparse:
    
     block/blk-map.c:57:31: warning: incorrect type in argument 2 (different address spaces)
     block/blk-map.c:57:31:    expected void *addr
     block/blk-map.c:57:31:    got void [noderef] <asn:1>*ubuf
    
    However blk_rq_map_kern() needs one more local variable to handle it.
