I further wonder if these people would see appreciable gains from doing sutoc rather than doing openat(dirfd, "basename", flags, mode); If they did, I could also see openat being extended to allow dirfd to be a file fd, as long as pathname were NULL or a pointer to NUL. But with all the readx stuff being proposed, I bet they don't really need independent file offsets. That's, like, so *1970*s. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
