This patch set intend to exclude unnecessary hugepages from vmcore dump file.
This patch requires the kernel patch to export necessary data structures into
vmcore: "kexec: export hugepage data structure into vmcoreinfo"
http://lists.infradead.org/pipermail/kexec/2013-November/009997.html
This patch introduce two new dump levels 32 and 64 to exclude all unused and
active hugepages. The level to exclude all unnecessary pages will be 127 now.
Interesting. Why hugepages should be treated any differentely than normal
pages?
If user asked to filter out free page, then it should be filtered and
it should not matter whether it is a huge page or not?
Yes, free hugepages should be filtered out with other free pages. It
sounds reasonable.
But for active hugepages, I would offer user more choices/flexibility.
(maybe bad).
I'm OK to filter active hugepages with other user data page.
Any other comments?
Thanks
