| Subject: [PATCH 14/85] ext4: Limit number of links that can be created by ext4_link() |
| |
| (cherry picked from commit b05ab1dc3795e6f997fb0d34f38fce5012533c3e) |
| |
| 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. |
