Hi, all Usually I find the following codes in Linux source that I can not understand clearly, it often happens when some error occured char *kaddr = kmap_atomic(page, KM_USER0); memset(kaddr, 0, PAGE_CACHE_SIZE); flush_dcache_page(page); kunmap_atomic(kaddr, KM_USER0); what is the usage of memset function? and in i386 flush_dcache_page(page) does nothing, why?
