Hi Mathieu, nice articles, now I can point my co-workers at it when they ask me
what this RCU stuff is all about :) I noticed that the article
http://lwn.net/Articles/573431/
says
"The hash table can then be allocated:
ht = cds_lfht_new(1, 1, 0, CDS_LFHT_AUTO_RESIZE, NULL);
The first 1 specifies the initial number of hash buckets in the table, the
second 1 specifies the minimum number of hash buckets, and the 0 specifies the
maximum number of hash buckets. All three quantities must be powers of two,
except for the special case of 0 for the third argument, which specifies an
unlimited maximum number of hash buckets."
However the rculfhash.h header doesn't say that the third argument can be zero.
All it says is:
* @max_nr_buckets: the maximum number of hash table buckets allowed.
* (must be power of two)
Best wishes, Duncan.

Hi,
Paul McKenney, Lai Jianshan, Josh Triplett and myself just published a series
of articles on Userspace RCU on Linux Weekly News. You can find the top-level
article at this URL:
https://lwn.net/Articles/573424/
Those articles introduce the Userspace RCU library, explaining how to use RCU
and the data structures it contains. Access to those articles is restricted to
LWN subscribers for a week after publication, and should be freely available
afterward.
Feedback is welcome!
Thanks,
Mathieu
