From c95c267a461475c6c2bac5c3f23c567e5360589c Mon Sep 17 00:00:00 2001 From: Kyle Evans Date: Fri, 10 Jul 2020 00:43:45 +0000 Subject: [PATCH] shm_open2: Implement SHM_GROW_ON_WRITE Lack of SHM_GROW_ON_WRITE is actively breaking Python's memfd_create tests, so go ahead and implement it. A future change will make memfd_create always set SHM_GROW_ON_WRITE, to match Linux behavior and unbreak Python's tests on -CURRENT.
