must be drivers/cdrom/optcd.c::cdromread() (line 1601 in 2.5.64),
due to
char buf[CD_FRAMESIZE_RAWER];
and
#define CD_FRAMESIZE_RAWER 2646 /* The maximum possible returned bytes */
in include/linux/cdrom.h.

Ahh, ok so a lot less interesting. Also why I didn't catch it here. I'd
be inclining to just making buf global there.

Patch to cut that down below.

Gerd

==============================[ cut here ]==============================

This patch updates the v4l1-compat module. Changes:
* use f_op->poll() instead of do_select()
* reduce stack usage of the v4l1_compat_translate_ioctl function.
* misc fixes here and there.
