From: Yu Kuai <yukuai3@xxxxxxxxxx>

Changes in v2:
- don't use test/set_bit() for new field, because unsigned long will
cause that some field can't be placed in the first cacheline(64 bytes),
use unsigned int for new field and test/set/clear it like 'bio->bi_flags'.

Yu Kuai (2):
block: introduce new field flags in block_device
block: warn once for each partition in bio_check_ro()
