Subject: [PATCH 0/3] x86/ftrace: Make created trampolines not call direct code
Date: Wed, 22 Apr 2020 12:25:39 -0400 [thread overview]
Message-ID: <20200422162539.808362933@goodmis.org> (raw)
Peter,
These three patches are built on top of your patch series.
This is what I was thinking of having. This isn't fully tested
(as your patch series is still running on my test suite).
-- Steve
Steven Rostedt (VMware) (3):
x86/ftrace: Make non direct case the default in ftrace_regs_caller
x86/ftrace: Only have the builtin ftrace_regs_caller call direct hooks
x86/ftrace: Do not jump to direct code in created trampolines
