------- Comment From ankigarg.com 2008-05-29 02:08 EDT------- The patches have supposed to be present in -60 kernel (based on -rt11). Verifying if the interface works now or not. ------- Comment From ankigarg.com 2008-05-29 07:26 EDT------- I tried the systemtap marker interface on the latest -60 kernel and found that it is not working. I confirm again that it is working on 2.6.25 based rt kernels. The required patches are mentioned in comment #1. Posting them to the mailing list. ------- Comment From ankigarg.com 2008-05-29 07:27 EDT------- (In reply to comment #8) > I tried the systemtap marker interface on the latest -60 kernel and found that > it is not working.

Got to first generate patches against the latest RT kernel. Will send it once that is done. ------- Comment From ankigarg.com 2008-05-30 08:07 EDT------- Attaching the patch here. With this, the interface works fine. Created attachment 307190 [details]
Fix marker/stap interface
------- Comment From ankigarg.com 2008-06-01 07:53 EDT------- Patch from comment #11 has been pulled into -62 MRG kernel. Marking this as FAT. ------- Comment From ankigarg.com 2008-06-02 02:19 EDT------- I have verified that this is resolved with the patch. The interface is working fine in the -62 kernel. Closing this bug from our end. ------- Comment From ankigarg.com 2008-06-02 02:21 EDT------- Sripathi, leaving it in ACCEPTED for you to close. closing I realize this is closed, but some problem crept in either with the final patch, or with patch stacking.
In kernel-rt-2.6.24.7-146, I see the following
% grep getopt *
marker-stap-interface-for-MRG.patch:- while ((opt = getopt(argc, argv, "i:I:cmso:aw")) != -1) {
marker-stap-interface-for-MRG.patch:+ while ((opt = getopt(argc, argv, "i:I:mso:awM:K:")) != -1) {
I propose this additional patch:
--- linux-2.6.24.7.i686/scripts/mod/modpost.c
+++ linux-2.6.24.7.i686.new/scripts/mod/modpost.c
