From 8cae8cd89f05f6de223d63e6d15e31c8ba9cf53b Mon Sep 17 00:00:00 2001
From: Eric Sandeen <sandeen@redhat.com>
Date: Tue, 13 Jul 2021 17:49:23 +0200
Subject: seq_file: disallow extremely large seq buffer allocations
There is no reasonable need for a buffer larger than this, and it avoids
int overflow pitfalls.
Fixes: 058504edd026 ("fs/seq_file: fallback to vmalloc allocation")
