Message-Id: List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable To: linux-ia64@vger.kernel.org Hello, A customer requires for his internal application a more strict implementati= on of the VM : -> When malloc returns a non-NULL pointer the memory is really available= ! How can I obtain this behavior using RedHat AS 2.1 kernel 2.4.18-e12 ? I know that Alan Cox has a patch and that a lot of job is currently done in= kernel 2.5 . This patch is partially integrated in the kernel 2.4.18-e12 delivered with = the RedHat Advanced Server 2.1.=20 But there is a difference between the documentation about overcommit_memor= y in sysctl/vm.txt and the code really implemented in mm/mmap.c Is there any reason for that ? Thanks for your help Thierry CARRON=20 > HP Centre de Comp=E9tence France * +33 (0).450.094.031
