The patch titled
Improve the removed sysctl warnings
has been removed from the -mm tree. Its filename was
improve-the-remove-sysctl-warnings.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Improve the removed sysctl warnings
From: ebiederm@xxxxxxxxxxxx (Eric W. Biederman)
Don't warn about libpthread's access to kernel.version. When it receives
-ENOSYS it will read /proc/sys/kernel/version.
If anything else shows up print the sysctl number string.
