We use BAR5 on two devices in legacy mode. Both of those reserve all the

Translation: You want to hand-wave away an obvious regression that YOU have created with your fix-to-a-fix.

It's not regressing anything.

False:

2.6.0 - 2.6.19: libata guarantees that all PCI BARs are reserved to the libata driver.

2.6.20: no guarantee that all PCI BARs are reserved to libata driver. Real-life ata_piix example already provided, where a PCI BAR is no longer reserved to the driver.

2.6.21 - infinity: libata guarantees that all PCI BARs are reserved to the driver.
