Apologizes if this is not relevant. I tried to compile Ceph client against a Lucid Ubuntu (Ubuntu 2.6.32-24-server), the master backport does not compile complaining for a missing definition of WQ_NON_REENTRANT. Not an expert of Kernel workqueues but I understand that this mechanism was introduced in a post subversion of current Ubuntu stable. Am I wrong assuming that the backport should not use Concurrency-managed workqueues? Is there a workaround for this? Again, sorry if this is not relevant.
