MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-ID: <104970.1690300714.1@warthog.procyon.org.uk> Date: Tue, 25 Jul 2023 16:58:34 +0100 Message-ID: <104971.1690300714@warthog.procyon.org.uk> X-Scanned-By: MIMEDefang 3.1 on 10.11.54.4 Precedence: bulk List-ID: X-Mailing-List: linux-m68k@vger.kernel.org Rather than adding a fchmodat2() syscall, should we add a "set_file_attrs()" syscall that takes a mask and allows you to set a bunch of stuff all in one go? Basically, an interface to notify_change() in the kernel that would allow several stats to be set atomically. This might be of particular interest to network filesystems. David
