And the boogeyman might really exist too. This is just hypotetical hand-waving. > where it could be preferred to use 8K stacks instead of 4K.

Fedora kernels have been built with 4K stacks for a long time. (Since even before the option went upstream). The only things that have been reported to have problems with 4KB stacks are.. - NDISwrapper / driverloader. (Shock, horror - no-one cares). - XFS when used in conjunction with RAID Fixed now ? (Though Neil Brown does have a pending patch for md to make that use less stack, which will also help). - Reiser4 Fixed 'soon'. > When on the other hand the 4K stacks are set as default, leaving the > option in, instead of removing it, these possible situations, when > found, could be resolved (temporarilly) by switching back to 8K > stacks. > > After a while having 4K stacks as default would be a better time to > decide whether to remove the option or not instead of now. This is what was proposed not long after the option got merged. "After a while" has passed by quite a stretch.
