Subject: Add fchmodat2() - or add a more general syscall?

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.
