[PATCH] ocfs2: remove redundant assignment to variable free_space
Posted by Colin Ian King 4 years, 5 months ago
Variable free_space is being initialized with a value that is not read,
it is being re-assigned later in the two paths of an if statement. The
early initialization is redundant and can be removed.
