Commit Message

Aleksandar Markovic Jan. 11, 2020, 3:40 p.m. UTC 
From: Aleksandar Markovic <amarkovic@wavecomp.com>

Both FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR accept a pointer to
the structure

struct file_clone_range {
	__s64 src_fd;
	__u64 src_offset;
	__u64 src_length;
	__u64 dest_offset;
};

as their third argument.

These ioctls were relatively recently introduced, so the "#ifdef"
guards are used in this implementation.
