Date: Tue, 17 Jan 2023 15:08:01 +0800 [thread overview]
Message-ID: <20230117070806.3857142-1-yukuai1@huaweicloud.com> (raw)
From: Yu Kuai <yukuai3@huawei.com>
changes in v4:
- a litter code optimization to make it easier to understand in patch
4.
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
