[PATCH] 2.5.7 IDE 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...
