Subject: [lttng-dev] [RFC PATCH liburcu 0/2] Remove RCU requirements on hash
	table destroy
Message-ID: <1496178620-14755-1-git-send-email-mathieu.desnoyers@efficios.com>

The RCU lock-free hash table currently requires that the destroy
function should not be called from within RCU read-side critical
sections. This is caused by the lazy resize, which uses the call_rcu
worker thread, even though all it really needs is a workqueue/worker
thread scheme.

Implement an internal workqueue API in liburcu, and use it instead of
call_rcu in rculfhash to overcome this limitation.

Mathieu Desnoyers (2):
  Implement urcu workqueues internal API
  Use workqueue in rculfhash
