    Subject[PATCH 0/4] loop: enable different physical blocksizes
    Date
    Currently the loop driver just simulates 512-byte blocks. When
    creating images for virtual machines it might be required to use
    a different physical blocksize (eg 4k for S/390 DASD).
    This patchset extends the current LOOP_SET_STATUS64 ioctl to
    set the logical and physical blocksize by re-using the existing
    'init' fields, which are currently unused.

    As usual, comments and reviews are welcome.

    Hannes Reinecke (4):
    loop: Enable correct physical blocksize
    loop: Remove unused 'bdev' argument from loop_set_capacity
    loop: Add 'lo_logical_blocksize'
    loop: Pass logical blocksize in 'lo_init[0]' ioctl field
