<linux/fscrypt.h> defines ioctl numbers using the macros like _IOWR() which are defined in <linux/ioctl.h>, so <linux/ioctl.h> should be included as a prerequisite, like it is in many other kernel headers. In practice this doesn't really matter since anyone referencing these ioctl numbers will almost certainly include <sys/ioctl.h> too in order to actually call ioctl(). But we might as well fix this.
