Hi Chuck, hi Steve, In Debian, as you might have heard there is a 64bit time_t transition[1] ongoing affecting the armel and armhf architectures. While doing so, nfs-utils was found to fail to build for those architectures after the switch, reported in Debian as [2]. Vladimir Petko from Ubuntu has as well filled it in [3]. [1]: https://lists.debian.org/debian-devel-announce/2024/02/msg00005.html [2]: https://bugs.debian.org/1067829 [3]: https://bugzilla.kernel.org/show_bug.cgi?id=218540 The report is full-quoted below. Vladimir Petko has created a patch in the bugzilla which I'm attaching here as well. If this is not an acceptable format due to missing Signed-off's I'm attaching a variant with a Suggested-by for Vladimir to properly credit the patch origin. Let me know if that works. I changed it slightly and only casting to long long, and made it almost checkpatch clean.
