This is why I inserted pte_none() for each page_table in case of read fault too. If read access fault occured for the address "addr". It is completely unnecessary to check by pte_none() to the page_table for "addr". Because page_table_lock has never been released until do_anonymous_page returns (in case of read access fault) But there is not any guarantee that the page_tables for addr+PAGE_SIZE, addr+2*PAGE_SIZE, ... have not been mapped yet. Anyway, I will try your V2 patch. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
