From c0d39e65ba324390eb0ffb60661ab12104e5fcc7 Mon Sep 17 00:00:00 2001 From: Namjae Jeon Date: Sun, 17 Mar 2013 17:26:53 +0900 Subject: [PATCH] f2fs: fix return values from validate superblock validate super block is not returning with proper values. When failure from sb_bread it should reflect there is an EIO otherwise it should return of EINVAL. Returning, '1' is not conveying proper message as the return type.
