Subject: [net-next v2 PATCH 0/3] page_pool: followup changes to restore tracepoint features
Date: Sat, 16 Nov 2019 12:22:32 +0100 [thread overview]
Message-ID: <157390333500.4062.15569811103072483038.stgit@firesoul> (raw)
This patchset is a followup to Jonathan patch, that do not release
pool until inflight == 0. That changed page_pool to be responsible for
its own delayed destruction instead of relying on xdp memory model.
As the page_pool maintainer, I'm promoting the use of tracepoint to
troubleshoot and help driver developers verify correctness when
converting at driver to use page_pool. The role of xdp:mem_disconnect
have changed, which broke my bpftrace tools for shutdown verification.
With these changes, the same capabilities are regained.
