--- Comment #3 from P Fudd <sourceware.org at ch dot pkts.ca> ---
Hi...

I'm using CentOS 6.5, and I'm finding the same thing:
---------------
# stap -v -e 'probe vfs.read {printf("read performed\n"); exit()}'
Pass 1: parsed user script and 96 library script(s) using
198468virt/26680res/3108shr/24072data kb, in 170usr/10sys/178real ms.
semantic error: while resolving probe point: identifier 'kernel' at
/usr/share/systemtap/tapset/linux/vfs.stp:768:18
        source: probe vfs.read = kernel.function("vfs_read")
                                 ^

        source: probe vfs.read {printf("read performed\n"); exit()}
                      ^

semantic error: no match

---------------

If I add '--download-debuginfo -vv' to that command line, it does the
following:
---------------
# stap --download-debuginfo -vv -e 'probe vfs.read {printf("read performed\n");
exit()}'

-------------------

I take it that CentOS has its own debug repository that I should be looking at?
