From eb31e2f63d85d1bec4f7b136f317e03c03db5503 Mon Sep 17 00:00:00 2001 From: Amir Goldstein Date: Sun, 24 Nov 2019 21:31:45 +0200 Subject: utimes: Clamp the timestamps in notify_change() Push clamping timestamps into notify_change(), so in-kernel callers like nfsd and overlayfs will get similar timestamp set behavior as utimes. AV: get rid of clamping in ->setattr() instances; we don't need to bother with that there, with notify_change() doing normalization in all cases now (it already did for implicit case, since current_time() clamps).
