oops.. sorry .. but why i didnot get a build failure after this?
ok, got it ...
#define OBD_FREE_LARGE(ptr, size) \
do { \
kvfree(ptr); \
} while (0)
the variable is actually not used. I will make a v2 and send
tomorrow. today is a day of silly mistakes :(

It's probably best to wait for a bit at this point.
Julia is going to send in a bunch of patches actually getting rid of

And then whatever stuff surfaces would be easier to see.
Thanks!

I have compile tested this. I looked through the history and it seems
to never have been used. I wonder if we can remove the locking as well.
