THP for ext4, page table manipulation primitives
Subsystems (2)
Hello,
I would like to attend the summit this year.
===
One topic I would like to discuss would be huge pages for ext4 and filesystems with backing storage in general. There's patchset that I have hard time upstreaming. I hope having talk about this in person would help moving it forward.
===
The other topic: the work on 5-level paging made more obvious that we need better way to deal with page tables. Having different data-types per page table level plus set of helpers to deal with each of them doesn't scale. It worked okay of 2- and 3- level page tables. For 5-, it's getting rather ugly.
And having different types/helpers to deal with different page table levels makes it harder to integrate huge pages into generic code path:
having separate code path for each page size is not very future proof approach.
