This partially applies the following commit to reduce the complexity of a Xen-4.20 patch: > xenopsd-xc: do not try keep track of free memory when planning NUMA nodes (CA-411684) > > Free memory is now properly accounted for because the memory pages are claimed > within the NUMA mutex, so there's no need to have double tracking. > > On top of that, this code never increased the free memory, which means that it > always reached a point where it was impossible to allocate a domain into a > single numa node. > Signed-off-by: Pau Ruiz Safont <[email protected]> However it doesn't actually drop the free memory accounting code, so: No functional change Signed-off-by: Edwin Török <[email protected]>

There is also a spec change to go with this for Xen-4.20 that updates the patch, I've linked this PR from that one. |
