[PATCH v3 2/4] fs: Introduce task path helpers

[sashiko-bot at kernel.org]

> From: Chen Linxuan <me at black-desk.cn>
> 
> Introduce helpers that acquire a referenced struct path for a task's
> executable, root, and working directory. Reuse them for procfs task
> links and AppArmor executable-path handling instead of duplicating file
> and path reference handling at each call site.
