Changes in v3:
 - add patch 1 from Ming, swap bd_inode layout with bd_openers and
 bd_size_lock;
 - change bd_flags from u32 to u16 in patch 2, prevent to affect layout of
 other fields;

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'.

Ming Lei (1):
  block: move .bd_inode into 1st cacheline of block_device

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