Failure to build misc/lib_memfd.c

[fdcavalcanti]

I just rebased my current fork and can't compile anymore. Something to do with misc/lib_memfd.c.
Here's the information:

misc/lib_memfd.c: In function 'memfd_create':

Maybe someone who worked on it could check?

Have you tried to run make menuconfig and save defconfig? I think that you need to refresh your configuration file after #9513

Thanks for the info. That fixed it.
