[PATCH v1 0/3] Refactor Landlock access mask management

From: Mickaël Salaün

Hi,

To simplify code for new access types [1], add 2 new helpers:
- landlock_merge_access_masks()
- landlock_filter_access_masks()

The last patch uses these helpers to optimize Landlock scope management
like with filesystem and network access checks.
