Cover letter [RESEND][PATCH 0/5] perf: Clean ups and simplifications
This is a resend from: https://lore.kernel.org/linux-trace-kernel/[email protected]/
It cleanly applied on top of the latest tip/perf/core:
448f97fba901 ("perf: Convert mmap() refcounts to refcount_t")
The ongoing work to support sframes[1] in the kernel required a few clean ups to the perf kernel side. Instead of having these changes in the ongoing work, there's no reason they cannot be applied now.
These are just clean ups to the perf code to help simplify the updates that will be made later.
