[PATCH v4 13/19] linux-user: Add support for FIFREEZE and FITHAW ioctls

[Aleksandar Markovic]

From: Aleksandar Markovic <address@hidden>

Both FIFREEZE and FITHAW ioctls accept an integer as their third
argument.

All ioctls in this group (FI* ioctl) are guarded with "#ifdef", so the
guards are used in this implementation too for consistency (however,
many of ioctls in FI* group became old enough that their #ifdef guards
could be removed, bit this is out of the scope of this patch).
