      Feature, enhancement: "-A" option was added
      Reason: Tracking conflicts between inodes with multiple hard links is memory intensive (especially on large file systems)
      Result: Users can now disable tracking inodes with multiple hard links, which allows "setfiles" usage on memory constrained systems.

      What were you trying to do that didn't work?

      Relabel a filesystem.

      What is the impact of this issue to you?

      Customer impact because they cannot do virt-v2v conversions (RHEL-111165).

      Please provide the package NVR for which the bug is seen

      It's whatever the version is in RHEL 9.6-z. However this also happens upstream (in Fedora Rawhide), so it seems to be an unresolved upstream bug.

      How reproducible is this bug?:

      Very.

      Steps to reproduce

      I created 15 million & 30 million files and placed them under /usr/lib/modules/.

      I then ran:

      # setfiles -F -C -T 16 /etc/selinux/targeted/contexts/files/file_contexts /usr/lib/modules/big

      I observed the memory usage using /usr/bin/time and valgrind massif. The valgrind results show a very obvious memory leak over time (see attachment).
