Subject[PATCH v3 0/3] block: warn once for each partition in bio_check_ro()
Date
From: Yu Kuai <yukuai3@huawei.com>

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()
