Subject: [PATCH v2 tip/core/rcu 16/39] rcu: Add single-element dequeue functions to rcu_segcblist
Date: Mon, 17 Apr 2017 16:45:03 -0700	[thread overview]
Message-ID: <1492472726-3841-16-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170417234452.GB19013@linux.vnet.ibm.com>

This commit adds single-element dequeue functions to rcu_segcblist.
These are less efficient than using the extract and insert functions,
but allow more precise debugging code.  These functions are thus
expected to be used only in debug builds, for example, CONFIG_PROVE_RCU.
