TCP buffer tuner was failing to load on 6.9 and later. CO-RE relocation for sk_userlocks in struct sock was the cause; the problem is sk_userlocks changes from a bitfield to a plain u8 and the vmlinux.h that was generated had the old representation. We can use a Linux version check to guard check of sk_userlocks. Reported-by: HippieMitch <https://github.com/HippieMitch> Signed-off-by: Alan Maguire <[email protected]>
