From c1f1f91d2183b91c684900b529b6c336ad3dd27c Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Thu, 5 May 2011 14:16:32 +0300 Subject: UBIFS: fix inode size debugging check failure This patch fixes a problem with the following symptoms: UBIFS: deferred recovery completed UBIFS error (pid 15676): dbg_check_synced_i_size: ui_size is 11481088, synced_i_size is 11459081, but inode is clean UBIFS error (pid 15676): dbg_check_synced_i_size: i_ino 128, i_mode 0x81a4, i_size 11481088 It happens when additional debugging checks are enabled and we are recovering from a power cut. When we fixup corrupted inode size during recovery, we change them in-place and we change ui_size as well, but not synced_i_size, which causes this failure. This patch makes sure we change both fields and fixes the issue.
