docs: fix ext4 documentation table formatting problems
It turns out that the latex table formatters lay out table columns with the exact proportional widths given in the table metadata, even if text overflows outside the box. This was not caught during the initial import because the HTML renderers are smart enough to fudge the table. Fix the table column width formatting problems in the data structures and algorithms documentation so that we don't have squashed columns. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
