Hi, I just filed on bugzilla (bz2421) regarding redefined errors with rcu_dereference_protected() and kfree_rcu() macros since the latest RHEL6.3's kernel (2.6.32-279.22.1.el6.x86_64). http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2421 Could anyone give me comments on this, please? Thanks Ihara
