Subject: [PATCH 0/4 V2] rcu: implement call_srcu()
Date: Mon, 19 Mar 2012 16:12:10 +0800 [thread overview]
Message-ID: <1332144734-9375-1-git-send-email-laijs@cn.fujitsu.com> (raw)
These patches are the second version of the
"[RFC PATCH 5/5 single-thread-version] implement per-domain single-thread state machine call_srcu()"
These patches are on the top of paulmck/linux-rcu.git/rcu/srcu
(3c8975b51a7bed5dd993c5c4eab245a121bdc728)
I noticed this branch has patch "implement Peter's checking algorithm"
applied, so the pathes are rebased on 3c8975b51 and are tested based on
Peter's algorithm.
Except the rebasing, only 2 changes:
Refactor the srcu_advance_batches() as Peter's suggestion.
Impletement synchronize_srcu() with fast path awared.
- old version just calls call_srcu() and waits.
- Ftrace shows new synchronize_srcu() cost 6us when fast path.
Lai Jiangshan (4):
fix for peter's algorithm
use "int trycount" instead of "bool expedited"
add call_srcu()
add srcu torture
