Subject: [PATCH 0/2] loop: support different blocksizes

Hi all,

the loop device already contains rudimentary support for blocksizes
other than 512 bytes, so this patchset enables the loop device
to use a different blocksize.
The new module parameter 'lbs' specify the blocksize to use,
or '0' to use the blocksize of the underlying device (which defaults
to PAGE_SIZE for files).
Eventually it might be useful to select the blocksize per device, but
the interface for that will need to be discussed.

Hannes Reinecke (2):
  loop: Display correct physical blocksize
  loop: Add module parameter 'lbs' to set logical blocksize
