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
fchmodat2() is a simple addition that fits well with the existing syscalls. It fixes an oversight in fchmodat(). IMO we should just add fchmodat2(), and not get sidetracked by trying to add some super-generalized syscall instead. That can always be done later. - Eric
