Re: ebtables-2.0.10-1: a build problem

[Bart De Schuymer <bdschuym@pandora.be>]

Hello Sergei,

Thanks for the report.
I finally figured out I have to run "make headers_install" in the kernel 
source directory to get sanitized headers. That removes the need for 
this __EXPORTED_HEADERS__ stuff. I'll be releasing an updated version 
later this week.
