Subject: Re: [PATCH v1 11/11] locks: give the blocked_hash its own spinlock
Date: Tue, 4 Jun 2013 07:46:40 -0700 [thread overview]
Message-ID: <20130604144640.GA7730@infradead.org> (raw)
In-Reply-To: <51ADF789.70906@samba.org>
Having RCU for modification mostly workloads never is a good idea, so
I don't think it makes sense to mention it here.
If you care about the overhead it's worth trying to use per-cpu lists,
though.
