+Subject: [PATCH] pam: Do not use tally2 if faillock is present
+
+From pam 1.4.0 release notes:
+
+Deprecated pam_tally and pam_tally2: these modules are no longer built
+by default and will be removed in the next release, use pam_faillock
+instead.
+https://github.com/linux-pam/linux-pam/releases/tag/v1.4.0
+
+Fixes #1313
