Description of problem: When using the ksm module, as per the LWN (http://lwn.net/Articles/328013/ ) news article, the customer believes that there should be some statistics shown for it in the /sys directory. http://lwn.net/Articles/328013/ Version-Release number of selected component (if applicable): How reproducible: Every time. Steps to Reproduce: 1. modprobe ksm 2. find -iname ksm* 3. wait. Actual results: No files found. Expected results: Tunables/statics reported as per the LWN document. Additional info: This problem was visible in 5.4 snap5.
Changing component to kvm, where the ksm module is shipped.
The version of ksm inside rhel 5.4 doesnt show statistics... it is little bit diffrent version than what the mainline have and does not have sysfs support... Is this a really bug after all?
(In reply to comment #4) > > Is this a really bug after all? Not necessarily. It was reported so it can be at least documented in case the users refer to the upstream KSM guide.

Newer features, such as exporting statistics on the /sys filesystem, that are implemented upstream are not in the version shipped in this release.
So I'm closing this issue (see comment #7,8)
