Hi, I am not sure why we have: " EAGAIN fork() cannot allocate sufficient memory to copy the parent's page tables and allocate a task structure for the child. " but it doesn't seem to reflect the reality. The text seems to be there from the time when man-pages were moved to git so there is no history for it. Unless I am missing something we need the patch below. Thanks! --- >From 9d56f4b46d604fc52aed6d87aac8fa5719ede058 Mon Sep 17 00:00:00 2001 From: Michal Hocko <mhocko@xxxxxxx> Date: Tue, 3 Feb 2015 16:34:45 +0100 Subject: [PATCH] fork.2: EAGAIN is not reported when task allocation fails The man page currently claims: " EAGAIN fork() cannot allocate sufficient memory to copy the parent's page tables and allocate a task structure for the child. " but the kernel reports both dup_task_struct and dup_mm failures as ENOMEM to the userspace. This seems to be the case from early 2.x times so let's simply remove this part.
