RELATIME has been around since 2006 now. The workable fixes to relatime (the always update once per 24 hours) you only just comitted - and did come from a vendor. It also looks btw that we don't want to have a "relatime" option and a "strictatime" option and a "relatimebutdoitevery24hrs" option. All three of these are the same thing so it should (regardless of default choice) be relatime=n n = 0 ('update if its more than 0 seconds out of date') = strictatime n = MAXINT (basically equals relatime) n = 24hrs (the new 'fixed' relatime but not too relative) n = anything else - user tuned Alan -- To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/
