device: if BLKPBSZGET is unavailable, enforce 512
If there is no define for BLKPBSZGET - we have hard time how to decrypt physical block size - we can't use here block_size, since this is usually 4k while we need to use 512b.
FIXME: find some better way, until that enforce value 512. Eventually we could also try to put in:
+#ifndef BLKPBSZGET +# define BLKPBSZGET _IO(0x12,123) +#endif
but this will still not work well on old kernels. --- lib/device/dev-io.c | 3 ++- 1 files changed, 2 insertions(+), 1 deletions(-)
