| |
This patch enables 4k stacks by default.
4k stacks have become a well-tested feature used fore a long time in Fedora and even in RHEL 4.
There are no known problems in in-kernel code with 4k stacks still present after Neil's patch that went into -mm nearly two months ago.
Defaulting to 4k stacks in -mm kernel will give some more testing coverage and should show whether there are really no problems left.
Keeping the option for now should make the people happy who want to use the experimental -mm kernel but don't trust the well-tested 4k stacks.
