From: Thomas Gleixner <redacted> The netfilter code relies only on the implicit semantics of local_bh_disable() for serializing wt_write_recseq sections. RT breaks that and needs explicit serialization here. Reported-by: Peter LaDow <redacted> Signed-off-by: Thomas Gleixner <redacted>

I'm trying these out right now. We've applied these patches to 3.0.36-rt58 (rather than pull in the full 3.0.48-rt72 -- too much risk for us right now to do a full kernel change). I am setting up a 3.0.48-rt72-rc1 fixture as well to test the release candidate. Thanks, Pete
