What steps will reproduce the problem?
1. Patch does not apply
2. Manually apply patch (see attachment)
2. Install sreadahead to start early in boot
3. Pack file of size 0 is created
And
4. echo open >/sys/kernel/debug/tracing/current_tracer
5. echo 1 >/sys/kernel/debug/tracing/tracing_enabled
6. Run some commands that open files.
7. No data in /sys/kernel/debug/tracing/trace
What is the expected output?
Pack file should contain some entries, and the trace should contain some
entries.
What version of the product are you using? On what operating system?
1.0, x86_64 Debian Linux, 2.6.28.2
Please provide any additional information below.
The kernel patch was obviously not intended for 2.6.28.2, since it didn't
apply, so manually applying (and fixing names like using DEFINE_TRACE
instead of DECLARE_TRACE) may not be good enough.
It would be nice if there was a patch that applies to 2.6.28.2, and has
been tested to work with it.
