Previously we coalesced windows by expanding the first overlapping one and making the second invalid. But we never look at the expanded first window again, so we fail to notice other windows that overlap it. For example, we coalesced these: [io 0x0000-0x03af] // #0 [io 0x03e0-0x0cf7] // #1 [io 0x0000-0xdfff] // #2 into these, which still overlap: [io 0x0000-0xdfff] // #0 [io 0x03e0-0x0cf7] // #1 The fix is to expand the *second* overlapping resource and ignore the first, so we get this instead with no overlaps: [io 0x0000-0xdfff] // #2 [bhelgaas: changelog] Reference: https://bugzilla.kernel.org/show_bug.cgi?id=62511 Signed-off-by: Alexey Neyman <stilor@att.net> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |
