There is only a single driver (sgi_ide) which hasn't been moved over to[1] which were a pain in the ass to untangle and debug during development,
it's really time for it to die..
Outside of the patch series in question, how to we expedite the
euthanasia of IDE? What explicit features/support are we missing through
libata that would need to be added, before we can git rm drivers/ide/ ?
libata.
But this is for an old Itanium-based server only, and even SGI didn't
press us to have this ported.
(And we have disabled the IDE drivers since SLES11, where we still support
Itanium.)
Cheers,
Hannes
