Hi! This is the second version of the BPF/RT patch set which makes both coexist nicely. The long explanation can be found in the cover letter of the V1 submission: https://lore.kernel.org/r/20200214133917.304937432@xxxxxxxxxxxxx The following changes vs. V1 have been made: - New patch to enforce preallocation for all instrumentation type programs - New patches which make the recursion protection safe against preemption on RT (Mathieu) - New patch which removes the unnecessary recursion protection around the rcu_free() invocation - Converted macro to inline (Mathieu) - Added explanation about the seccomp loop to the changelog (Vinicius) - Fixed the explicitely typos (Jakub) - Dropped the migrate* stubs patches and merged them into the tip tree. See below. The series applies on top of: git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-for-bpf-2020-02-20 This tag contains only the two migrate stub commits on top of 5.6-rc2 and can be pulled into BPF. The commits are immutable and will be carried also in tip so further changes in this area can be applied.
