Prehistory: Linus and others.

Since start of 1994: Mark Lord. Everybody was happy until mid 1998 (2.1.111),
when, after a discussion about problems a few people had with DMA
Linus patched linux/drivers/block/Config.in:

-        bool '     Generic PCI bus-master DMA support' CONFIG_BLK_DEV_IDEDMA
+       # Either the DMA code is buggy or the DMA hardware is unreliable. FIXME.
+        #bool '     Generic PCI bus-master DMA support' CONFIG_BLK_DEV_IDEDMA

and Mark wrote: "I will not be updating the IDE driver again until the
linux/drivers/block/Config.in file is restored to its pre-111 state."

Since Fall 1998 (2.1.122): Andre Hedrick.

Recent history is known.

(Lots of other people also did useful work on IDE. I will not try to list
names since I would forget some.)

Of course, "IDE maintainer" implies work on the interface with the hardware
and work on the interface with the block I/O subsystem of the kernel.
Some people know all about the hardware, others know much less about
hardware but have good ideas about the driver interface.
There is no reason to force the "IDE maintainer" to be a single person.
