From: Aleksandar Markovic <amarko...@wavecomp.com>
FITRIM ioctl accepts a pointer to the structure
struct fstrim_range {
__u64 start;
__u64 len;
__u64 minlen;
};
as its 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).
