Yeah the bug was 2 years old when I started patching it and now it is 4 years old... > This mail does not get any reply according to linux-ext4 patchwork, so > could I ping it? I suppose, I think the patch is authored according to the maintainer requirements, but I'm happy to revise and resend it if it no longer applies. Arnd and others suggested to maybe use F_SETFL instead: https://lore.kernel.org/linux-fsdevel/CAK8P3a2SN2zeK=dj01Br-m86rJmK8mOyH=gHAidwSPgKAEthVw@xxxxxxxxxxxxxx/ I am happy to do it either way by need to have some input from the maintainer (Ted). Maybe someone else on the fsdevel list want to chime in? Maybe any FS maintainer can actually apply this? Yours, Linus Walleij
