From b05ab1dc3795e6f997fb0d34f38fce5012533c3e Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 29 Aug 2009 21:08:08 -0400 Subject: [PATCH] ext4: Limit number of links that can be created by ext4_link() In ext4_link we need to check using EXT4_LINK_MAX, and not EXT4_DIR_LINK_MAX(), since ext4_link() is creating hard links of regular files, and not directories.
