[1/2] block: move .bd_inode into 1st cacheline of block_device commit: fad907cffd4bde7384812cf32fcf69becab805cc [2/2] block: warn once for each partition in bio_check_ro() commit: 67d995e069535c32829f5d368d919063492cec6e Best regards,
From: Yu Kuai <yukuai3@huawei.com> Changes in v4: - remove the patch to add 'bd_flags', and add a new field 'bool bd_ro_warned' in patch 2. 'bd_flags' will be added once 'bd_inode' is removed from other thread. 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'.
