But file system page cache writes only call flush_dache_page() if the page has a non-empty i_mmap_shared list.

No, it examines both lists, the problem is not there.
The issue seems to be some confusion about whether the test program in question is actually mmap()'ing the area with PROT_WRITE set, and if so why the test case isn't passing because in such a case the page will have a non-empty i_mmap_shared list. - 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/
