    [PATCH] remove kiobufs · 2dcb8ff9
    Andrew Morton authored
    This patch from Christoph Hellwig removes the kiobuf/kiovec
    infrastructure.
    
    This affects three subsystems:
    
    video-buf.c:
    
       This patch includes an earlier diff from Gerd which converts
        video-buf.c to use get_user_pages() directly.
    
       Gerd has acked this patch.
    
    LVM1:
    
       Is now even more broken.
    
    drivers/mtd/devices/blkmtd.c:
    
       blkmtd is broken by this change.  I contacted Simon Evans, who
       said "I had done a rewrite of blkmtd anyway and just need to convert
       it to BIO.  Feel free to break it in the 2.5 tree, it will force me
       to finish my code."
    
    Neither EVMS nor LVM2 use kiobufs.  The only remaining breakage
    of which I am aware is a proprietary MPEG2 streaming module.  It
    could use get_user_pages().
