Will Manjaro enable MGLRU Patch on its 6.1 Kernel release?

[sparsa]

I read that MGLRU Patch promises good performance improvents. It is now included in 6.1 kernel but is not enabled by default. Will manjaro enable this while releasing 6.1 Kernel?

Would be greate. It give huge perfomance boost. Maple Tree as well

It should probably remained disabled by default.

Once mainlined, the next obstacle for the involved Google engineers is to get MGLRU to the point that it could be safely enabled by default. Before considering it by default, they need much more performance testing and benchmarking to ensure MGLRU is in good shape and won’t regress existing workloads. They also hope to integrate MGLRU with eBPF to open up even more possibilities.

MGLRU was already enabled in Kernel 6.1, not 6.0.

Check if it is enabled:
$ zgrep LRU /proc/config.gz

CONFIG_LRU_GEN=y
CONFIG_LRU_GEN_ENABLED=y
# CONFIG_LRU_GEN_STATS is not set
CONFIG_DAMON_LRU_SORT=y
CONFIG_LRU_CACHE=m

See the Kernel document.

Are you on the Stable branch?

The latest available kernel for me on Stable is 6.0 (and for LTS, 5.15).

@winnie

Are you on the Stable branch?

No, the testing branch and Manjaro kernel 6.0.

I checked the unstable branch with Manjaro kernel 6.1 in VM.

Same here testing 6.1 (unstable branch) on Qemu
6.1.1 is in pipeline:
Linux 6.1.1-rc1
