    block: Kill bi_destructor · 4254bba1
    Kent Overstreet authored
    Now that we've got generic code for freeing bios allocated from bio
    pools, this isn't needed anymore.
    
    This patch also makes bio_free() static, since without bi_destructor
    there should be no need for it to be called anywhere else.
    
    bio_free() is now only called from bio_put, so we can refactor those a
    bit - move some code from bio_put() to bio_free() and kill the redundant
    bio->bi_next = NULL.
    
    v5: Switch to BIO_KMALLOC_POOL ((void *)~0), per Boaz
    v6: BIO_KMALLOC_POOL now NULL, drop bio_free's EXPORT_SYMBOL
    v7: No #define BIO_KMALLOC_POOL anymore
