Hi Marcelo,

Configure.help contains the help text below that sounds more like a
comment to a patch than a helpful help message for a user of a stable
kernel:

+CONFIG_IDE_TASKFILE_IO
+  This is the "Jewel" of the patch.  It will go away and become the new
+  driver core.  Since all the chipsets/host side hardware deal w/ their
+  exceptions in "their local code" currently, adoption of a
+  standardized data-transport is the only logical solution.
+  Additionally we packetize the requests and gain rapid performance and
+  a reduction in system latency.  Additionally by using a memory struct
+  for the commands we can redirect to a MMIO host hardware in the next
+  generation of controllers, specifically second generation Ultra133
+  and Serial ATA.
+
+  Since this is a major transition, it was deemed necessary to make the
+  driver paths buildable in separtate models.  Therefore if using this
+  option fails for your arch then we need to address the needs for that
+  arch.
+
+  If you want to test this functionality, say Y here.

Could anyone provide a more useful help text?

TIA
Adrian
