The 'memory_idle_ms_percentiles' array in DAMON_STAT is updated frequently by the kernel to reflect the latest idle time statistics. Marking it as '__read_mostly' is inappropriate for data that is regularly written to, as it can lead to cache pollution in the read-mostly section. Remove the '__read_mostly' annotation to accurately reflect the variable's usage pattern.
