Unclear No caller of stashIdentity/takeIdentity is visible, so what feature this supports is not established.
What
A sandbox file-lane class gains two new methods, stashIdentity and takeIdentity, which track a per-path device/inode identity using an LRU-style (least-recently-used) eviction cache. If the eviction-tracking set overflows, the lane enters a 'poisoned' state.
Why
No code calling these new methods is visible in this change, so it's unclear what feature this identity tracking supports yet.
