Subject: [PATCH] make-bcache: fix guessing of "block_size" to use BLKSSZGET
Using stat.st_blocksize is wrong:
that is the linux buffer cache granularity,
it is tunable, and defaults to 4k.
This caused bcache to default to create devices with
logical_block_size = 4k, potentially breaking otherwise healthy disk
or file system images unnecessarily.
e.g. some xfs image previously created with 512 byte "sector size"
would, once bcache'd, refuse to mount with
mount: function not implemented
device supports 4096 byte sectors (not 512)
We want the logical_block_size here.

This makes supporting -U more annoying; dropping that for the moment,
