vbox dkms fix - How to include fix for linux, but not linux-lts?

All, Doug, A header include is requires for 6.4.12, but not for LTS. How do I modify the PKGBUILD to apply the change only when building the module for linux and not linux-lts. I chose a simple sed -i to include the needed header: # fix 6.4.11 include requirement sed -i 's|#include <linux/inetdevice.h>|&\n#include <net/gso.h>|' "${_extractdir}/src/vboxhost/vboxnetflt/linux/VBoxNetFlt-linux.c" The problem is that LTS doesn't like the additional include. I suspect it will take some makefile patch instead of a change of the source file so LTS can build without the new header. How best to do this? -- David C. Rankin, J.D.,P.E.
