feat(sampling) Remove tracepoints based process switch recording support #272

Closed cvonelm closed 1 year ago

cvonelm commented 1 year ago

This PR removes support for process switch recording based on tracepoints.

lo2s now requires support for PERF_RECORD_SWITCH, which was added in the 4.3 kernel and is widely backported to older systems. Neither Taurus nor the Levante installation at DKRZ lack PERF_RECORD_SWITCH support.
