Subject: [ltt-dev] [PATCH RFC urcu 0/2] v2 allow multiple URCU flavors in one executable
Date: Tue, 12 Apr 2011 20:51:10 -0700 [thread overview]
Message-ID: <20110413035110.GA26549@linux.vnet.ibm.com> (raw)
Hello!
The following set of patches permits a single executable to use
multiple flavors of URCU without resorting to linker tricks. The
approach is to map each flavor to a different namespace. The patches
are as follows:
1. Provide pthread_atfork-friendly interfaces.
2. Map symbols to allow multiple flavors of URCU to be mixed.
3. Apply feedback from v1 review.
4. Extend symbol mapping to include defer_rcu().
This does not yet centralize pthread_atfork() handling, nor does it
combine all the binaries into a single dynamic library. This latter
is enabled by the name mapping.
Further thoughts?
Thanx, Paul
