Re: [mpls-linux-devel] mpls patch vs. rt patch

[James R. L. <jl...@mi...>]

I'm sure the RT patch doesn't like my locking technique.  Spinlocks are
a big no-no in the RT world ...  probably not going to work together at
this time.  At some point I will modify my locking scheme to not use spinlo=
cks
which will allow the RT patch and MPLS patch to play nicely with each other.
