In general lines should stay under 80 columns. There are a few
exceptions to the rule (e.g., print strings), but most of the long lines
you have in this patch need to conform.

The above would be more readable as
static const
struct filters cm_id_valid_filters[MAX_NUMBER_OF_FILTERS] = {
{ .name = "link", .is_number = false },
{ .name = "lqpn", .is_number = true },
...
Definitely do not split between struct and filters.
