-Subject: [PATCH 3/3] liqxanmod: deduplicate sched_nr_latency definition
+Subject: [PATCH 3/3] liqxanmod: no-op for XanMod 6.19+ (sched_nr_latency removed)
 
-Both XanMod and Zen patches add a definition of sched_nr_latency in
-kernel/sched/fair.c. When both patch sets are applied together this
-causes a duplicate-symbol link error.
+XanMod 6.19 removed sched_nr_latency and the old sysctl_sched_latency
+API in favour of sysctl_sched_base_slice. The deduplication this patch
+previously performed is no longer needed.
 
-This patch removes the XanMod-side definition and declaration, leaving
-the Zen-side definition in place. The LiqXanMod sysfs bridge
-(liqxanmod_sysfs.c) writes sched_nr_latency directly, so both the
-XanMod throughput profile and the Zen latency profile continue to work
-correctly.
