From 723590ed52d244b025f10a8e2f54c2f57ed02b4d Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Sat, 15 Aug 2009 08:43:22 +0200 Subject: splice: update mtime and atime on files Splice should update the modification and access times on regular files just like read and write. Not updating mtime will confuse backup tools, etc... This patch only adds the time updates for regular files. For pipes and other special files that splice touches the need for updating the times is less clear. Let's discuss and fix that separately.
