The last email I found related to that is in "[PATCH] fs: ext4: Sign-extend tv_sec after ORing in epoch bits", but the patch that I actually thought was ready to land was "[PATCH v8 1/2] ext4: Fix handling of extended tv_sec (bug 23732)" and the matching e2fsprogs patch: http://lkml.org/lkml/2014/2/13/667 http://lkml.org/lkml/2014/2/13/670 Would be nice to get them landed, since we have less than 20 years left, and at some point there will be embedded systems or VMs using ext4 that may live long enough to hit the bug... Cheers, Andreas
