Title:
[Feature] Crystal Ridge - Use FS DAX radix tree as a cache to service
page faults
Status in intel:
Triaged
Status in linux package in Ubuntu:
Incomplete
Bug description:
Description
We already keep the sector in the radix tree as part of the
exceptional entry. For page faults where we already have an
exceptional entry, use this information directly from the radix tree
instead of calling into the filesystem to get a block mapping. This
should show a measurable performance improvement, which should be
reported as motivation for the patches.
Target Kernel:TBD
Target Release: 19.10
