# \[PATCH\] ARM: mark kernelmode mem{cpy,set} non-experimental - From: Linus Walleij \ - Date: 2012-09-09 08:12:28 - List: linux-arm-kernel - Page: https://ratatoskr.run/linux-arm-kernel/2012/09/8617675 - Thread: https://ratatoskr.run/linux-arm-kernel/2012/09/8617675/t.md ```text This feature was added in 2009, I've been using it off and on and never had any problems with it on my systems. I cannot see why it needs to be marked experimental, make it a normal feature and let us discover its possible shortcomings as people try to turn it on instead.
