[Babel-users] Removing source-specific for older kernels [was: Higher CPU usage since 1.9.x leads to instability on slow devices]

[Juliusz Chroboczek]

Folks, please be so kind as to check

  https://github.com/jech/babeld/pull/65

This is based on Antonin's work, but should in principle be able to deal
gracefully with older kernels.  I'll test it later this week-end, and if
nobody object, merge it next week.
