Nobody merged it and Ingo got bored of pushing it. I sent it earlier, but nobody came up with an especially good argument for the configurability and everyone seemed to want to paint the patch pink with yellow polka dots, so I gave up and just sent a minimal one in the hope that nobody could find anything to complain about. > Just a minor nit, but the patch description (not included in the patch itself) > "at least once a day" isn't particularly accurate given that the patch enforces > at least a day [minus a second or so] has elapsed since the last update.

If mtime is changed then atime will be updated on the next access, so you can easily have more than one atime update a day. -- Matthew Garrett | mjg59@srcf.ucam.org -- 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/
