Changes from 1.1.27 to 1.1.28

These changes are archived on ftp.crynwr.com:pub/kchanges and http://www.crynwr.com/kchanges. I cannot answer questions about Linux -- I merely summarize the kernel patches after reading them. I try to make them useful to everyone, but kernel hackers should take them with a grain of salt and read the patches themselves. The patch file is patch28.gz

• Improved sardonic lp error message. Some over-literal person must have gotten one.
• Remember the pointer to the driver for serial drivers.
• NFS buffer file size was just a little too big.
• Handle dead sockets properly in /proc/net/{tcp,udp,raw}.
• Include TCP fastpath again.
• Add a missing release_sock call.
• SCSI changes from Eric Youngdale:
  • More changes to eventually support loadable modules. Mainly we want to use linked lists instead of arrays because it is easier to dynamically add and remove things this way.
  • Quite a bit more work is needed before loadable modules are possible (and usable) with scsi, but this is most of the grunge work.
  • * Linux 1.1.28 released.
  • scsi.c, scsi.h (allocate_device, request_queueable): Change argument from index into scsi_devices to a pointer to the Scsi_Device struct.
  • Throughout: Change all calls to allocate_device, request_queueable to use new calling sequence.
  • Throughout: Use SCpnt->device instead of scsi_devices[SCpnt->index]. Ugh - the pointer was there all along - much cleaner this way.
  • scsi.c (scsi_init_malloc, scsi_free_malloc): New functions - allow us to pretend that we have a working malloc when we initialize. Use this instead of passing memory_start, memory_end around all over the place.
  • scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use scsi_init_malloc, remove all arguments, no return value.
  • scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd structs.
  • scsi.c (scsi_dev_init): Set up for scsi_init_malloc. (scan_scsis): Get SDpnt from scsi_init_malloc, and refresh when we discover a device. Free pointer before returning. Change scsi_devices into a linked list.
  • scsi.c (scan_scsis): Change to only scan one host. (scsi_dev_init): Loop over all detected hosts, and scan them.
  • hosts.c (scsi_init_free): Change so that number of extra bytes is stored in struct, and we do not have to pass it each time.
  • hosts.h: Change Scsi_Host_Template struct to include "next" and "release" functions. Initialize to NULL in all low level adapters.
  • hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked list scsi_hosts, linked together with the new "next" field.
