From 2e0a547164b1384a87fd3500a01297222b0971b0 Mon Sep 17 00:00:00 2001 From: Richard Guy Briggs Date: Fri, 3 Feb 2023 16:35:14 -0500 Subject: fanotify: Ensure consistent variable type for response The user space API for the response variable is __u32. This patch makes sure that the whole path through the kernel uses u32 so that there is no sign extension or truncation of the user space response.
