Subject[PATCH] 2.5.7 IDE 27
Thu Mar 21 03:17:48 CET 2002 ide-clean-27

- Make for less terse error messages in ide-tape.c.

- Replaced all timecomparisions done by hand with all the proper timer_after()
commands.

- Remove the drive niec1 mechanisms alltogether. There are several reasons for
this:

1. The code implementing it is nonintelliglible and therefore propably
broken.

2. If we have to invent somethig about sceduling drive IO, it should be done
on the BIO level.

3. We may in fact interleave with the IO sceduling on the upper layers and
the results of two overlapping signal filters overlapped with each other can
be disasterous to the overall throughput. (In fact they *are* most of the
time.)

4. It was not working if you had intermixed modes on different drives
DMA versus PIO.

5. Our goal is to have a driver which is able to share the badwidth
properly and shouldn't needing this kind of "tuning".

- Remove unused nice2 from disk struct.

- Rename channel member of ata_channel to unit and device to dev to
just prevent wrong interpretations. This prevents constructs like
channel->channel...
