The patch titled
make sysctl/kernel/core_pattern and fs/exec.c agree on maximum core filename size
has been removed from the -mm tree. Its filename was
make-sysctl-kernel-core_pattern-and-fs-execc-agree-on-maximum-core-filename-size.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: make sysctl/kernel/core_pattern and fs/exec.c agree on maximum core filename size
From: Dan Aloni <da-x@xxxxxxxxxxxxx>
Make sysctl/kernel/core_pattern and fs/exec.c agree on maximum core
filename size and change it to 128, so that extensive patterns such as
'/local/cores/%e-%h-%s-%t-%p.core' won't result in truncated filename
generation.
