    bcache: Use standard utility code · 8e51e414
    Kent Overstreet authored
    Some of bcache's utility code has made it into the rest of the kernel,
    so drop the bcache versions.
    
    Bcache used to have a workaround for allocating from a bio set under
    generic_make_request() (if you allocated more than once, the bios you
    already allocated would get stuck on current->bio_list when you
    submitted, and you'd risk deadlock) - bcache would mask out __GFP_WAIT
    when allocating bios under generic_make_request() so that allocation
    could fail and it could retry from workqueue. But bio_alloc_bioset() has
    a workaround now, so we can drop this hack and the associated error
    handling.
