Subject: [PATCH v3 0/4] vdpa_sim_blk: add support for flush, discard, and write-zeroes

by the following patches that add handling of flush, discard, and
write-zeroes requests.

v3:
- fixed clang issue reported by kernel test robot <lkp@...el.com>
- used le*_to_cpu() to access virtio_blk_discard_write_zeroes fields
