FWIW, to make it clear: fsmount(2) in this series actually does *NOT* attach it to the tree. Commit message definitely needs updating - as it is, it's +SYSCALL_DEFINE5(fsmount, int, fs_fd, unsigned int, flags, unsigned int, ms_flags, + void *, reserved4, void *, reserved5) PS: IMO these reserved... arguments are in bad taste; if anyone has good reasons for that practice in ABI design, I'd like to hear those. -- To unsubscribe from this list: send the line "unsubscribe linux-api" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
