Subject: [git pull] PCI changes for 2.6.30
Please consider pulling my PCI tree from
git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6 linux-next
There are some real changes in here, notably Alex's changes to the core to add
real hotplug support, Matthew's multiple MSI support, and Yu's SR-IOV support.
Overall, v12n users should be happy with this set of changes. And as is
customary we got a good collection of fixes from the usual suspects: Kenji-san,
Yinghai, and Bjorn. Oh and Alpha has support for sysfs PCI resources now,
thanks to a commit from Ivan.
I note you've been having some tree management discussions with people this
time around, so I figured it would be good to describe how I've been handling
things.
I generally have two branches going: for-linus and linux-next. The for-linus
branch rarely gets merge commits or rebases. Merges will generally only
happen if I have some dependencies with another tree (like ACPI), and rebases
only occur when I need to drop a patch. Other than that it's just fast
forwards from pulling your tree (after you've pulled mine) and commits for
new patches.
I try to keep the linux-next branch a superset of my for-linus branch at the
request of my downstream developers. This means periodic rebasing after the
merge window closes, but it's generally important to get your latest stuff
into that branch so that downstream developers don't have to fight with bugs
that have been fixed upstream. This isn't pain free (downstream developers
with large patchsets then have to rebase their stuff) but so far it seems
like the path of least pain for our purposes, probably because I haven't
started pulling trees from downstream (yet). If I did, I of course would
avoid rebasing at that point...
Anyway hope this pull is ok. I went through every warning by hand to make
sure none were caused by PCI commits, but that was with the bits in this
tree, which are -rc8 vintage.
Thanks,
