Thanks for the investigation.
After reverting, two test cases got PASS out of four reported failure cases.
 ltp-crypto-tests:
     * af_alg02 - still failing - Hung and time out
     * af_alg05 - still failing - Hung and time out
  ltp-syscalls-tests:
     * keyctl07 - PASS
     * request_key03 - PASS

Please suggest the way to debug / fix the af_alg02 and af_alg05 failures.
