This function is only used by online fsck, so let's move it there. In the next patch, we'll fix it to work properly and to require that the caller hold the AGI buffer locked. No major changes aside from adjusting the signature a bit. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Dave Chinner <dchinner@redhat.com>
