## AI overview

A proposal for ARM64 Linux would let administrators set kernel stack size at boot, avoiding a kernel rebuild and potentially reducing memory use, particularly on Android. The RFC discusses smaller stack sizes and possible per-task sizing.

## Source excerpt

A proposal was posted this week to the Linux kernel mailing list by a Google engineer to make it easier for ARM64 Linux to adjust the kernel stack size. The motivation for doing so to configure the kernel stack size during boot time is on reducing system memory consumption...
