    pnfsblock: alloc short extent before submit bio
    
    As discussed earlier, it is better for block client to allocate memory for
    tracking extents state before submitting bio. So the patch does it by allocating
    a short_extent for every INVALID extent touched by write pagelist and for
    every zeroing page we created, saving them in layout header. Then in end_io we
    can just use them to create commit list items and avoid memory allocation there.

    pnfsblock: limit bio page count
    
    One bio can have at most BIO_MAX_PAGES pages. We should limit it bec otherwise
    bio_alloc will fail when there are many pages in one read/write_pagelist.

    pnfsblock: don't spinlock when freeing block_dev
    
    bl_free_block_dev() may sleep. We can not call it with spinlock held.
    Besides, there is no need to take bm_lock as we are last user freeing bm_devlist.

    This function returns a big endian value.  The implementation in

    "unsigned" instead.  It makes sparse complain:
