Subject: [PATCH 0/3] tracepoint static call fixes
Date: Thu,  5 Aug 2021 09:27:14 -0400	[thread overview]
Message-ID: <20210805132717.23813-1-mathieu.desnoyers@efficios.com> (raw)

This series fixes issues with tracepoint callback function vs data
argument mismatch when back-to-back registrations/unregistrations are
performed.

Those issues were introduced by the tracepoint optimizations using
static_call().

Thanks,

Mathieu
