@@ -35,7 +35,7 @@ invlpg instruction (or instructions _near_ it) show up high in
profiles. If you believe that individual invalidations being
called too often, you can lower the tunable:
- /sys/debug/kernel/x86/tlb_single_page_flush_ceiling
+ /sys/kernel/debug/x86/tlb_single_page_flush_ceiling
This will cause us to do the global flush for more cases.
Lowering it to 0 will disable the use of the individual flushes.
