Subject: [PATCH v2 0/2] block: warn once for each partition in bio_check_ro()

From: Yu Kuai <yukuai3@...wei.com>

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()
