SYZFAIL: coverage filter is full
pc=0x80007000c0008 regions=[0xffffffffbfffffff 0x243fffffff 0x143fffffff 0xc3fffffff] alloc=156 (errno 11: Resource temporarily unavailable)

For some reason, we pass non-kernel address to the coverage filter.

A more interesting question is why we pass the coverage filter data there at all -- the error happens on ci-upstream-kasan-gce-root and ci-upstream-kasan-gce-selinux-root. We do not specify any coverage filters in their configuration.

We do not specify any coverage filters in their configuration.

The coverage filter object is also used to track max cover, so it's always used when coverage is enabled.
