Please use present tense and a sane title, something like:

  fs: Move core dump functionality into its own file
  fs: Make core dump functionality optional

While looking at that code, there's also a few uglies in it, 
like:

These prototypes should move out of sched.h and into a 
coredump.h header or so.

If we are touching this code lets use the opportunity and do 
this right.

Note, I'd suggest to put any such further changes into separate, 
additional patches at the end: a cleanup patch, a header file 
introduction patch, etc. - and keep the "dumb code movement" 
chnage in the initial patch. This will make it all much easier 
to review.

Please also review the code for more uglies, the above was just 
a very quick stylistic scan.

Thanks,
