From 471e78cc7687337abd10626196f5addb30b01824 Mon Sep 17 00:00:00 2001 From: Michal Koutný Date: Tue, 11 Aug 2020 18:30:57 -0700 Subject: /proc/PID/smaps: consistent whitespace output format MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The keys in smaps output are padded to fixed width with spaces. All except for THPeligible that uses tabs (only since commit c06306696f83 ("mm: thp: fix false negative of shmem vma's THP eligibility")). Unify the output formatting to save time debugging some naïve parsers. (Part of the unification is also aligning FilePmdMapped with others.)
