    [SCSI] qla4xxx: bug fixes · 477ffb9d
    David C Somayajulu authored
    The included patch fixes the following issues:
    
    1. qla3xxx/qla4xxx co-existence issue which can result in a lockup
    when qla3xxx driver is unloaded, or when ifdown; ifup is performed on
    one of the interfaces correponding to qla3xxx. This is because qla4xxx
    HBA supports one ethernet and iscsi interfaces per port. Both iscsi
    and ethernet interfaces share the same state machine. The problem has
    to do with synchronizing access to the state machine in the event of a
    reset
    
    2. mutex_lock() is sometimes not followed by mutex_unlock() prior to
    invoking a msleep() in qla4xxx_mailbox_command()
