Hi all,
Sander reports an Xen pci-passthrough regression caused by
commit cffe0a2b5a34c95a4dadc9ec7132690a5b0f6687 ("x86, irq: Keep
balance of IOAPIC pin reference count"). This patch set tries to
fix it.
Patch 1 is a fix for another issue found during fixing the regression.
Patch 2 is a hotfix for the regression and should be targeted for v3.19.
Patch 3 is the foundamental fix for the regression and should be targeted
at v3.20.
Hi Sander,
Could you please help to test by:
1) only apply patch 1 and patch 2
2) and then apply patch 3 ontop of patch 1/2.
Thanks!
Gerry
