Pass 4: compilation failed.  Try again with another '--vp 0001' option.

Please try systemtap 1.7, or build one out of
<git://sourceware.org/git/systemtap.git>.  Newer kernels sometimes
break systemtap assumptions; these are fixed pretty quickly in the
source tree, and get rolled into later releases.

Please report any further problems at [off-list ref],
including /usr/bin/stap-report output, if able.

  ok, but i'm curious ... i took a quick look at earlier kernels and i
don't see where "struct hlist_head" *ever* had a "next" member field
that is required by this version of systemtap (1.4).

  can you clarify which kernel version(s) would have worked with this
version of systemtap?  thanks.
