Jeff, I shall send all the sata patches which I have at you one single time
and I shall then drop the lot. So please don't flub them.
I'll then do a rc1-mm2 without them.
hm, this is looking like a lot of work for not much gain. Rafael, are
you able to do a quick chop and tell us whether these:
pci-move-pci_vdevice-from-libata-to-core.patch
pata_cs5530-suspend-resume-support-tweak.patch
ata-fix-platform_device_register_simple-error-check.patch
initializer-entry-defined-twice-in-pata_rz1000.patch
pata_via-suspend-resume-support-fix.patch
sata_nv-add-suspend-resume-support.patch

user-of-the-jiffies-rounding-patch-ata-subsystem.patch
libata-fix-oops-with-sparsemem.patch
sata_nv-fix-kfree-ordering-in-remove.patch
libata-dont-initialize-sg-in-ata_exec_internal-if-dma_none-take-2.patch
pci-quirks-fix-the-festering-mess-that-claims-to-handle-ide-quirks-ide-fix.patch
are innocent?
Yes, they are.
We all really appreciate your patience :) This is good feedback.
To narrow down some more, does applying 2.6.20-rc1 + the attached patch
work? (ignoring -mm tree altogether)
The attached patch should /basically/ be the contents of Andrew's
git-netdev-all patch.
