106 It's also possible to limit defrag efforts in the VM to generate
108 regions or to never try to defrag memory and simply fallback to regular
110 time to defrag memory, we would expect to gain even more by the fact we
117 	echo always >/sys/kernel/mm/transparent_hugepage/defrag
118 	echo defer >/sys/kernel/mm/transparent_hugepage/defrag
119 	echo defer+madvise >/sys/kernel/mm/transparent_hugepage/defrag
120 	echo madvise >/sys/kernel/mm/transparent_hugepage/defrag
121 	echo never >/sys/kernel/mm/transparent_hugepage/defrag
171 invoke defrag algorithms synchronously during the page faults, it
172 should be worth invoking defrag at least in khugepaged. However it's
173 also possible to disable defrag in khugepaged by writing 0 or enable
174 defrag in khugepaged by writing 1::
176 	echo 0 >/sys/kernel/mm/transparent_hugepage/khugepaged/defrag
177 	echo 1 >/sys/kernel/mm/transparent_hugepage/khugepaged/defrag
