Re: [PATCH for-next v3 1/2] block: introduce pi_size field in blk_integrity

Hi Anuj!

Introduce a new pi_size field in struct blk_integrity to explicitly
represent the size (in bytes) of the protection information (PI)
tuple. This is a prep patch.

Instead of introducing a new thing which means what the old thing was
supposed to mean, I'd prefer to change the existing tuple_size to
metadata_size. There aren't that many occurrences in the code so it
would be a largely mechanical change.

This patch would then become the second in the series introducing a
pi_tuple_size member to explicitly define the size of the PI tuple (if
any).
