Digging through history:
4a30131e7dbb ("[PATCH] Fix some problems with truncate and mtime semantics.")
6e656be89999 ("[PATCH] ftruncate does not always update m/ctime")
These are pretty old commits (>10years); has anything changed since
then relative to the required semantics for truncate/ftruncate?
Thanks,
