Subject: [PATCH 1/2] fs: move struct linux_dirent into headers

Move the definition of linux_dirent to include/linux/dirent.h,
where the newer linux_dirent64 already lives. This is done in
preparation for moving both of these struct definitions into uapi/
so userspace code doesn't need to duplicate them.
