Subject: libext2fs: external journal devices should not cause ext2fs_open2 to fail
X-Git-Url: http://git.kernel.org/?p=fs%2Fext2%2Fe2fsprogs.git;a=commitdiff_plain;h=341b52dfa8c2afc11d8410de9bd381b03e75c6af
libext2fs: external journal devices should not cause ext2fs_open2 to fail
This fixes a regression introduced in commit 79a9ab14 which caused
attempts to open external journals to fail due to overly strict
filesystem consistency checks.
