From 447e9a7c668113e85e2b6a7a330a3b517cae6c93 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 7 Jun 2022 12:49:36 +0200 Subject: [PATCH] tty/vt: consolemap: saner variable names in con_release_unimap() The function uses too vague variable names like i, j, k for iterators, p, q, p1, p2 for pointers etc. Rename all these, so that it is clear what is going on: - dict: for dictionaries. - d, r, g: for dir, row, glyph iterators -- these are unsigned now. - dir, row: for directory and row pointers. - glyph: for the glyph. - and so on... This is a lot of shuffling, but the result pays off, IMO.
