[PATCH 3/4] KVM: selftests: Play nice with EACCES errors in open_path_or_exit()

From: Sean Christopherson
Date: Fri May 16 2025 - 18:00:13 EST


Expand the SKIP conditions of the open_path_or_exit() helper to skip on
EACCES as well as ENOENT. Most often, lack of permissions to a file
needed by a KVM selftests is due to a file being root-only by default,
not because of any bug/misconfiguration that warrants failing a test.
