SubjectRe: [PATCH 10/13] tracing/uprobes: Fetch args before reserving a ring buffer
Sorry, I didn't read this series yet. Not that I think this needs my
help, but I'll try to do this a later...

GFP_KERNEL should be fine for uprobe handler.

However, iirc this conflicts with the patches from Jovi,
"Support ftrace_event_file base multibuffer" adds rcu_read_lock()
around uprobe_trace_print().

Steven, Jovi, what should we do with that patch? It seems that it
was forgotten.

I can take these patches into my ubprobes branch and then ask Ingo
to pull. But this will complicate the routing of the new changes
like this.

Oleg.
