This makes the setting unusable on Noble. [Test Plan] On Noble, start a systemd service with MemoryKSM=yes: $ systemd-run -u test-memory-ksm.service --wait -p MemoryKSM=yes /usr/bin/true On an affected system, this will fail immediately. Inspecting the journal will show why, e.g.: $ journalctl -u test-memory-ksm.service Oct 17 10:37:20 six (sleep)[1494131]: test-memory-ksm.service: Failed to set KSM: Invalid argument Oct 17 10:37:20 six systemd[1]: Started test-memory-ksm.service - /usr/bin/sleep infinity. Oct 17 10:37:20 six systemd[1]: test-memory-ksm.service: Main process exited, code=exited, status=245/KSM Oct 17 10:37:20 six systemd[1]: test-memory-ksm.service: Failed with result 'exit-code'. On a patched system, the unit should start/exit normally. [Where problems could occur] This patch simply adds missing arguments to the prctl call for PR_SET_MEMORY_MERGE. Problems would be isolated to the MemoryKSM= setting. [Other information] The patch is from upstream: https://github.com/systemd/systemd/commit/9bb89a55a235a3c64ec099bb86296d7fd1bb3302 [Original Description] In one of my working unit (service), I try to toggle the MemoryKSM boolean setting. Using any of: MemoryKSM=yes MemoryKSM=on MemoryKSM=true MemoryKSM=1 Results in: Sep 19 16:16:56 systemd[1]: Started XXX.service - XXX service. Sep 19 16:16:56 (e_server)[4487]: XXX.service: Failed to set KSM: Invalid argument Sep 19 16:16:56 systemd[1]: XXX.service: Main process exited, code=exited, status=245/KSM Sep 19 16:16:56 systemd[1]: XXX.service: Failed with result 'exit-code'. The following lines allow the service to start: MemoryKSM="yes" MemoryKSM="on" MemoryKSM="true" MemoryKSM="1" but still, MemoryKSM stays off: # systemctl show XXX.service | grep MemoryKSM MemoryKSM=no KSM is activated in my running kernel: # cat /boot/config-$(uname -r) | grep KSM CONFIG_KSM=y Using prctl (libc6 2.39-0ubuntu8.3) to toggle KSM inside a running process also works. I can read and set the memory_merge switch.
