From 7c83cc91ab1505e53ebfb99b1ea19ed1cf01c1b0 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 11 Mar 2011 17:15:55 +0200 Subject: UBIFS: save 128KiB or more RAM When debugging is enabled, we allocate a buffer of PEB size for various debugging purposes. However, now all users of this buffer are gone and we can safely remove it and save 128KiB or more RAM.
