Date: Fri, 28 Aug 2009 21:53:40 -0400 From: Theodore Ts'o <tytso@....edu> To: Ext4 Developers List <linux-ext4@...r.kernel.org> Cc: Theodore Ts'o <tytso@....edu> 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.
