tested: by me, with kernel patches posted at the same time
RHEL only. This is asked by SAP for their upcoming bigger VMs.
Upstream is going to use a more flexible limit of INT_MAX, but the patch
is not merged yet and enforcing the supported limit might be what we
want. In any case, bumping one number is not a big maintenance burden.
