Hi,
Here is the 5th version of the patchset for probe-cache and
initial SDT support which are going to be perf-cache finally.
The previous version is here; https://lkml.org/lkml/2016/4/26/179
This version fixes a build bug on "make build-test", removed
accepted patches, and fold buildid-cache style change and backward
compatibility patches.
IOW, just a cleanup version :)
TODOs are here, but I think it should involve kernel-side change
to complete.
- (perf record) Support SDT event recording directly
- (perf record) Support @FILE/@BUILDID suffix to record specific SDTs.
- (perf record) Try to unregister SDT events after record.
I just sent a patch enabling direct recording on SDT events implementing
1st and 3rd TODOs of the above list. Its based on your patches. Let me
know your thoughts on the same.

Thanks,

- (ftrace) Support multiple SDTs on single event.
Thank you,
