[PATCH 0/4] perf: support zstd-compressed kernel modules

[Ivan Shapovalov]

This extends in-perf zstd code to add an interface for streaming
decompression of an entire file, and uses that interface in dso.c to
support handling of zstd-compressed DSOs (e.g., zstd-compressed kernel
modules, as shipped by various distros including Arch).
