docker/secrets-0001-daemon-allow-directory-creation-in-run-secrets.patch
Aleksa Sarai cdaf1b8273 Accepting request 576039 from home:cyphar:containers:switch_patch_source
- Update patches to be sourced from https://github.com/suse/docker-ce (which
  are based on the upstream docker/docker-ce repo). The reason for this change
  (though it is functionally identical to the old patches) is so that public
  patch maintenance is much simpler.

Subject: [PATCH 1/2] daemon: allow directory creation in /run/secrets
Since FileMode can have the directory bit set, allow a SecretStore
implementation to return secrets that are actually directories. This is
useful for creating directories and subdirectories of secrets.
