You actually said this is/was documented and relied upon all over. http://thread.gmane.org/gmane.linux.ide/13184/focus=14486 (searching mailboxes more...) Oh, and the dropping of common PIO mode selection was agreed upon by Jeff and Alan. One way or the other, this only affects PATA devices and as long as all PATA LLDs guarantee that selection timing isn't violated, this can go. I thought PATA drivers still relied on this common denominator PIO mode configuration. I think it's Alan's call. > I'm curious what the motivation of this patch was? Hope my intentions are explained.
