------------------------------------------------------ From: Andrew Morton akpm@linux-foundation.org Subject: revert "memfd: improve userspace warnings for missing exec-related flags". Date: Sat Sep 2 03:59:31 PM PDT 2023

This warning is telling userspace developers to pass MFD_EXEC and MFD_NOEXEC_SEAL to memfd_create(). Commit 434ed3350f57 ("memfd: improve userspace warnings for missing exec-related flags") made the warning more frequent and visible in the hope that this would accelerate the fixing of errant userspace.

But the overall effect is to generate far too much dmesg noise.
