what''s the meaning of xchg()?
lartc-request,hello!
I find a line in tbf_change() in sch_tbf.c: ptab = xchg(&q->P_tab, ptab);
Can I consider that the pointers are exchanged between q->P_tab and ptab? as following:
prev=q->R_tab;
q->R_tab = rtab;
rtab = prev;
Is my understanding righ?

[PATCH 0/5] VT-d support for PV guests
...en/arch/x86/mm.c
to map/unmap IOMMU pages when the page types change. This might
not be the apropriate place to hook these calls.
The patches I''ve added are as follows:
xen-vtd-unmap.patch --- Make the VT-d iommu_unmap_page() code
actually do something close to useful.
xen-ptab-dump.path --- There''s no point in using ''current'' when an
IOMMU page fault is raised. Also, add some page type
statistics for DomPage debug output.
xen-iommu-pv.patch --- Add support for iommu_pv_enable boot
parameter and IOMMU assignment of PCI...
