Kirill A. Shutemov with faultaround patchset introduced
vm_ops->map_pages() for mapping easy accessible pages around
fault address in hope to reduce number of minor page faults.
This patch creates infrastructure to move the FAULT_AROUND_ORDER
to arch/ using Kconfig. This will enable architecture
Kirill A. Shutemov with faultaround patchset introduced
vm_ops-map_pages() for mapping easy accessible pages around
fault address in hope to reduce number of minor page faults.
This patch creates infrastructure to move the FAULT_AROUND_ORDER
