[Roman Kurakin <rik@cronyx.ru>]

Hi,

    Who is responsible person for applying patches to main tree?

This time I decide to send 2.5.5 patch version:

   I have found a bug. It is in support of serial cards which uses 
memory for
   I/O insted of ports. I made a patch for serial.c and fix one place, but
   probably the problem like this one could be somewhere else.
  
   If you try to use setserial with such cards you will get "Address in use"
   (-EADDRINUSE)
