Btrfs: move fs/btrfs/ioctl.h to include/uapi/linux/btrfs.h

Commit Message

Filipe Brandenburger Jan. 29, 2013, 6:04 a.m. UTC

The header file will then be installed under /usr/include/linux so that
userspace applications can refer to Btrfs ioctls by name and use the same
structs used internally in the kernel.
