From 6599fcbd01baf9d57e847db103d215ea4ec088f9 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 18 Oct 2010 10:00:40 +0300 Subject: [PATCH] UBIFS: do not allocate unneeded scan buffer In 'ubifs_replay_journal()' we allocate 'sbuf' for scanning the log. However, we already have 'c->sbuf' for these purposes, so do not allocate yet another one. This reduces UBIFS memory consumption while recovering.
