[PATCH] proc: fix smaps and meminfo alignment

From: Hugh Dickins
Date: Fri May 25 2018 - 07:56:40 EST


The 4.17-rc /proc/meminfo and /proc/<pid>/smaps look ugly: single-digit
numbers (commonly 0) are misaligned. Remove seq_put_decimal_ull_width()'s
leftover optimization for single digits: it's wrong now that num_to_str()
takes care of the width.

Fixes: d1be35cb6f96 ("proc: add seq_put_decimal_ull_width to speed up /proc/pid/smaps")
