Baokun Li 9e8e819f8f ext4: avoid overflow when setting values via sysfs ... When setting values of type unsigned int through sysfs, we use kstrtoul() to parse it and then truncate part of it as the final set value, when the set value is greater than UINT_MAX, the set value will not match what we see because of the truncation. As follows: $ echo 4294967296 > /sys/fs/ext4/sda/mb_max_linear_groups $ cat /sys/fs/ext4/sda/mb_max_linear_groups 0 So we use kstrtouint() to parse the attr_pointer_ui type to avoid the inconsistency described above. In addition, a judgment is added to avoid setting s_resv_clusters less than 0.
