Bug#695182: [RFC] Reproducible OOM with just a few sleeps

[paul.szabo@sydney.edu.au]

Dear Simon,

> So if he config sparse memory, the issue can be solved I think.

In my config file I have:

CONFIG_HAVE_SPARSE_IRQ=y
CONFIG_SPARSE_IRQ=y
CONFIG_ARCH_SPARSEMEM_ENABLE=y
# CONFIG_SPARSEMEM_MANUAL is not set
CONFIG_SPARSEMEM_STATIC=y
# CONFIG_INPUT_SPARSEKMAP is not set
# CONFIG_SPARSE_RCU_POINTER is not set

Is that sufficient for sparse memory, or should I try something else?
Or maybe, you meant that some kernel source patches might be possible
in the sparse memory code?

Thanks, Paul
