[Xen-devel] [PATCH 2/4] x86/vMSI-X: drop list lock

2016-06-08 Thread Jan Beulich
msixtbl_pt_{,un}register() already run with both the PCI devices lock and the domain event lock held, so there's no need for another lock. Just to be on the safe side, acquire the domain event lock in the cleanup function (albeit I don't think this is strictly necessary). Signed-off-by: Jan Beulic
