IT33132: JOURNAL BASED BACKUP WON'T RUN ON REDHAT 7.8 AND 8.2.

APAR status

• Closed as program error.

Error description

  extension attemps to load, the following error displayed in the
  terminal:
  insmod: ERROR: could not insert module filepath.ko: Operation
  not permitted
  ERROR: Failed to start filepath with error 1
  
  Affected versions:
  Backup-archive client v8.1 JBB kernel extension on RHEL 7.8 and
  RHEL 8.2
  Backup-archive client v7.1 JBB kernel extension on RHEL 7.8

Problem conclusion

• The mount structure changed in the Red Hat kernel.  Our filepath
  kernel extension was updated to handle that change while still
  maintaining backwards compatibility.  With this fix, the kernel
  extension loads successfully.
