In this version we support all erase units (not only ones, which are
powers of 2).
I put a restriction 1MiB for erase units just to filter possible
garbage. We can
increase this boundary, if needed.
Alignments with (bdev_discard_alignment() % s_blocksize != 0) are still
unsupported.
I have added mount options to specify erase unit and alignment in bytes.
This is
only for debugging purposes (to emulate real situations). Usage is the
following:
mount /dev/xxx -o discard,discard.unit=yyy,discard.offset=zzz /mnt
Thanks,
Edward.
