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() block/bdev.c | 15 ++++++++------- block/blk-core.c | 21 +++++++++++++++------ block/genhd.c | 15 +++++++++++---- block/ioctl.c | 6 +++++- include/linux/blk_types.h | 28 ++++++++++++++++++++++------ include/linux/blkdev.h | 5 +++-- 6 files changed, 64 insertions(+), 26 deletions(-) -- 2.39.2
