Subject: set_msi_affinity() vs. pci_restore_msi_state()
Date: Fri, 05 Mar 2010 16:03:52 +0000	[thread overview]
Message-ID: <4B9139780200007800033011@vpn.id2.novell.com> (raw)

Isn't the fact that the former updates the MSI message data without
updating the copy of it in memory a problem for the latter, i.e. won't
the latter restore stale information? While the problem (if there is one)
existed before c/s 20073, the fact that the vector now can change
seems to make the potential effect of this much worse.

Thanks, Jan
