it's _not_ 5k. Yes the kernel patch is 5k, but there is also an lvm.c
'file' which is a kernel module but is kernel code most definitely:

hell:~/LVM/0.4alpha> ls -l kernel/lvm.c
-rw-r--r-- 1 mingo mingo 67109 Jun 28 19:43 kernel/lvm.c

nowhere near 5k. Or we could just argue 'Linux RAID is only 10 lines of
support in the kernel'. (the rest is just 300k of module source code)
