…ted (requires >= v5.2) 1,global variable declaration will compile to .rodata/.bss section in ELF file. 2, haveMapMutabilityModifiers function will create ARRAY type ebpf map with BPF_F_RDONLY_PROG flag to detect system support in syscalls.go . 3. so need to remove global variable on kernel version less than 5.2 via haveMapMutabilityModifiers in cilium/ebpf/syscalls.go 4. more info cilium/ebpf@f5942f5 Signed-off-by: CFC4N <cfc4n.cs@gmail.com>

1,global variable declaration will compile to .rodata/.bss section in ELF file.
2, haveMapMutabilityModifiers variable will create
ARRAYtype ebpf map withBPF_F_RDONLY_PROGflag to detect system supported in syscalls.go .3. so need to remove global variable on kernel version less than 5.2 via haveMapMutabilityModifiers in cilium/ebpf/syscalls.go
