Merge tag 'landlock-6.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mic/linux

Pull landlock updates from Mickaël Salaün:
 "This brings two main changes to Landlock:

   - A signal scoping fix with a new interface for user space to know if
     it is compatible with the running kernel.

   - Audit support to give visibility on why access requests are denied,
     including the origin of the security policy, missing access rights,
     and description of object(s). This was designed to limit log spam
     as much as possible while still alerting about unexpected blocked
     access.

  With these changes come new and improved documentation, and a lot of
  new tests"
