Thanks for taking care of the autobuild failure, but....
To be exact, only utils/keytable depend on the (new) linux kernel bpf header, so
it would be sufficient for only v4l-utils to depend on headers >= 3.18 (or split
v4l-utils into the single utils with different dependencies)?
Or: the commit d6025b0e8c7f57b0f9390f987acc5eed57360d80 adds already a copy
of the linux/bpf.h header, maybe only the dependent linux/bpf_common.h file is
missing?
Regards,
Peter
