OK.
the single excessive slab cache instead of dumping all slab caches when
oom.
You meant to say
"to just dump all slab caches which excess 10% of the total memory."
While we are at it. Abusing calc_mem_size seems to be rather clumsy and
tt is not nodemask aware so you the whole thing is dubious for NUMA
constrained OOMs.
Since we just need the total memory size of the node for NUMA constrained
OOM, we should be able to use show_mem_node_skip() to bring in nodemask.
yes
to be more specific. This would work for the total number of pages
calculation. This is still not enough, though. You would also have to
filter slabs per numa node and this is getting more and more complicated
for a marginal improvement.
Yes, it sounds so. Basically, I agree with you to wait for a while to
see how the current implementation is doing.
Thanks,
Yang
