It's not a big deal, as f2fs use 32bits to index block device's address space, so there is at most 1 << 32 blocks in f2fs, we can not save more blocks than the number... If it overflows 32bits variable's space, it must be a bug. > > Signed-off-by: Daeho Jeong <daehojeong@...gle.com> Reviewed-by: Chao Yu <yuchao0@...wei.com> Thanks,
