[CC += linux-api@xxxxxxxxxxxxxxx] Hello William, Since this is a kernel-user-space API change, please CC linux-api@. The kernel source file Documentation/SubmitChecklist notes that all Linux kernel patches that change userspace interfaces should be CCed to linux-api@xxxxxxxxxxxxxxx, so that the various parties who are interested in API changes are informed. For further information, see https://www.kernel.org/doc/man-pages/linux-api-ml.html Aside from that, I've added a few other people/lists to CC that seem likely to be relevant. Some additional comments below. On Mon, May 11, 2015 at 4:07 AM, William Orr <will@xxxxxxxxxxxx> wrote: > Hey, > > Currently, Linux's fchmodat(2) doesn't honor the flags argument.

This seems an obviously sensible addition, and it was an obvious mistake not to have a 'flags' argument in the original system call (https://lwn.net/Articles/585415/). As well as getting us a proper POSIX compliant API (and one that is consistent with other implementations, such as FreeBSD), it allows for future behavior expansion via the 'flags' argument.
