[PATCH v1 2/9] landlock: Fix filesystem denial blocker reporting

[sashiko-bot at kernel.org]

> Filesystem topology denials are rendered with an empty blockers value
> because their blocker is identified by the request type instead of an
> access mask.
> 
> Introduce the private struct landlock_blockers to carry the request type
> and final missing access mask to filesystem and network denial
> tracepoints. Copy both members into named trace-record fields, then use
> the type to print change_topology for topology denials while preserving
> symbolic access masks for ordinary denials.
> 
> The request type lets typed BPF consumers distinguish topology denials
> from access denials. Keeping the native access mask in a pointer-reached
> field also lets CO-RE adjust existing programs' load width if
> access_mask_t grows.
