Subject: [S390] hypfs crashes with invalid mount option.
X-Git-Tag: v2.6.19-rc1~1298^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=388c571cffc4ae4e64f0786333e811308acbbc10;p=pandora-kernel.git

[S390] hypfs crashes with invalid mount option.

When an invalid mount option is specified, no root inode is created
for hypfs, hypfs_fill_super() returns with -EINVAL and then
hypfs_kill_super() is called. hypfs_kill_super() does not check if
the root inode has been initialized. This patch adds this check.
