Hi Gbadebo,

Are you applying the patch to a vanilla Linux kernel, or are you cloning Litmus directly from a litmus-rt repository?  I ask because CONFIG_FEATHER_TRACE works just fine in the Litmus code I cloned from github.

Do "git clone git://github.com/LITMUS-RT/litmus-rt.git" to clone the latest version of Litmus.

That said, FEATHER_TRACE still appears in the litmus-et-2013.1.patch file, so I don't know why anything would be broken.  Do you see the line "config FEATHER_TRACE" in litmus/Kconfig?

-Glenn
