Local fix

  • N/A
    

Problem summary

  • System may crash if a J2 filesystem gets corrupted.
    

Problem conclusion

  • Don't assert immediately when a filesystem corruption is
    detected. Instead, mark that filesystem alone as corrupt so
    that no attempts are made to read/write to it.
    

Temporary fix
