-Subject: [PATCH] revert "memfd: improve userspace warnings for missing
- exec-related flags".
-
-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.
