It could be sealed from creation. Agreed, VM_SEALED should be always for the "[uprobes]" vma, regardless of config options. ACK, but can't we do #ifdef CONFIG_64BIT /* VM is sealed, in vm_flags */ #define VM_SEALED _BITUL(63) + #else + #define VM_SEALED 0 #endif and then simply vma = _install_special_mapping(mm, area->vaddr, PAGE_SIZE, - VM_EXEC|VM_MAYEXEC|VM_DONTCOPY|VM_IO, + VM_EXEC|VM_MAYEXEC|VM_DONTCOPY|VM_IO|VM_SEALED, ? But I am fine either way, feel free to ignore. Oleg.
