> This needs more explanation than that one-liner comment. Make the > commit message explain why the new FOLL_TRIED flag exists. This patch actually is extracted from a 3.18 commit in the KVM tree, https://git.kernel.org/cgit/virt/kvm/kvm.git/commit/?h=next&id=234b239b. Here is how that patch uses the flag: /* * The previous call has now waited on the IO. Now we can * retry and complete. Pass TRIED to ensure we do not re * schedule async IO (see e.g. filemap_fault). */ down_read(&mm->mmap_sem); npages = __get_user_pages(tsk, mm, addr, 1, flags | FOLL_TRIED, pagep, NULL, NULL); -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
