[LTP] [PATCH v3] overcommit_memory: Fix integer overflow and 32-bit limits

[Petr Vorel]

Hi all,

> the overcommit settings.

> This fixes two problems on 32-bit systems. The first is seen with a
> integer overflow can occur when calculating sum_total * 2, if the

> Now the test runs correctly on low-memory 32-bit systems while avoiding
> both the overflow bug and virtual address space issues.

Thanks, also this patch merged!

Kind regards,
Petr
