There may be extreme case as below: For one section contains one segment, and there are total 100 segments with 10% over-privision ratio in f2fs partition, fggc_threshold will be rounded down to 460 instead of 460.8 as below caclulation: sbi->fggc_threshold = div_u64((u64)(main_count - ovp_count) * BLKS_PER_SEC(sbi), (main_count - resv_count)); If section usage is as: 60 segments which contain 460 valid blocks 40 segments which contain 462 valid blocks As valid block number in all sections is large than fggc_threshold, so none of them will be chosen as candidate due to incorrect fggc_threshold. Let's just soften the term of choosing foreground GC candidates. Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org> |
