Subject: [RFC v1 PATCH 0/7] bpf: Make RT friendly.
Date: Sat, 07 Dec 2019 16:03:57 -0800 (PST)
Message-ID: <20191207.160357.828344895192682546.davem@davemloft.net> (raw)


The goal of this patch set is to make the BPF code friendly in RT
configurations.

The first step is eliminating preemption disable/enable and replacing
it with local lock usage when full RT is enabled.

Likewise we also need to elide usage of up_read_non_owner() in the
stackmap code when full RT is turned on.
