      Running lustre_rmmod when kmemleak is disabled will produce spurious error messages for many subtests like:
      https://testing.whamcloud.com/gerrit-janitor/58788/testresults/conf-sanity2-zfs-rocky8.10_x86_64-rocky8.10_x86_64/conf-sanity.suite_log.oleg460-client.log

      lustre_rmmod: line 114: echo: write error: Device or resource busy
      lustre_rmmod: line 156: echo: write error: Device or resource busy
      unloading modules via unload_modules_local on: 'oleg460-server'
      oleg460-server: oleg460-server.virtnet: executing unload_modules_local
      oleg460-server: lustre_rmmod: line 114: echo: write error: Device or resource busy
      oleg460-server: lustre_rmmod: line 156: echo: write error: Device or resource busy
      start mds service on oleg460-server
      test-framework.sh: line 1033: echo: write error: Device or resource busy
      test-framework.sh: line 1034: echo: write error: Device or resource busy
      

      This makes it (incorrectly) appear that something is not working properly.

      These messages should be quieted.
