At this point, I run out of steam.

After the minor changes are committed, I could pull <= patchset #5 into #upstream immediately.

Great. Once I get your responses and sorts out AHCI EH, I'll make new git branch you can pull from. I can't wait to push those to #upstream. Managing 120 stacked patches was a nightmare. If I change something early in the series, even a simple/silly stuff, it causes a lot of rejects in later patches.

The upcoming ata_link patchset looks quite nice; that is definitely the direction I want to go.

Great.

I've already given hotplug plenty of thought (i.e. general design principles I like), so reviewing HP-related patchset should not take very long. I'll need to refresh my PM-related design thoughts a bit before diving into that patchset, so that might take several days to get to.

I'm still working on power applied together case because ahci is failing the first reset in a lot of cases. Waiting for several secs before hotplug reset solved the problem for sata_sil and sata_sil24 but ahci's problem seems to be a different one - it doesn't seem to update TF for the first FIS after hotplug reset. However, those changes are minor and wouldn't affect reviewing process, I think.

Thanks for reviewing and good night. :)
