[PATCH bpf-next 5/5] x86/bpf: enable EXECMEM_ROX_CACHE for BPF allocations
From: Mike Rapoport (Microsoft)
Date: Fri Jun 26 2026 - 14:43:30 EST
BPF core and x86 JIT use text poking and temporary writable buffers and
thus can handle ROX memory.
Enable ROX cache for EXECMEM_BPF when configuration and CPU features allow
that.
