Peter Zijlstra f3c0eba287 perf: Add a few assertions ... While auditing 6b959ba22d ("perf/core: Fix reentry problem in perf_output_read_group()") a few spots were found that wanted assertions. Notable for_each_sibling_event() relies on exclusion from modification. This would normally be holding either ctx->lock or ctx->mutex, however due to how things are constructed disabling IRQs is a valid and sufficient substitute for ctx->lock. Another possible site to add assertions would be the various pmu::{add,del,read,..}() methods, but that's not trivially expressable in C -- the best option is wrappers, but those are easy enough to forget.
