Subject: ext4: add module aliases for ext2 and ext3
X-Git-Url: https://bbs.cooldavid.org/git/?a=commitdiff_plain;h=51b7e3c9fbe7d22d4e355101e9a73b44fc5c9feb;p=net-next-2.6.git

ext4: add module aliases for ext2 and ext3

Add module aliases for ext2 and ext3 when CONFIG_EXT4_USE_FOR_EXT23 is
set.  This makes the existing user-space stuff like mkinitrd working
as is.
