tasklist_lock location

I wrote function into a kernel module that iterated through the current
tasks for statistics purposes to /proc/mymod. Following an example
from the procfs sources, I used (un)read_lock(&tasklist_lock) during the
time I was iterating throug them.

But a user using 2.2.10-smp complained that though he could compile my
module fine, upon insmod'ing it he got this problem:
mymod-smp-2.2.10: unresolved symbol tasklist_lock

Is there a config flag in the kernel sources that would lead to this
symbol not being created? Perhaps he didn't compile in a /proc
filesystem? I was just wondering where exactly it was defined, and
whether or not I have to tell him to enable a certain option, or if it's
a deeper issue. Thanks.
