From: Yu Kuai <yukuai3@huawei.com> changes in v3: - move some patches into separate patchset - don't return other error number for match_u64() in patch 1 - instead of checking user input separately, set page directly if 'bps + IOC_PAGE_SIZE' will overflow. Li Nan (2): blk-iocost: fix divide by 0 error in calc_lcoefs() blk-iocost: change div64_u64 to DIV64_U64_ROUND_UP in ioc_refresh_params() Yu Kuai (3): blk-iocost: check return value of match_u64() blk-iocost: don't allow to configure bio based device blk-iocost: read params inside lock in sysfs apis block/blk-iocost.c | 31 +++++++++++++++++++++++++------ 1 file changed, 25 insertions(+), 6 deletions(-)
