From 053800a84b942511054b51299db4430b3d1b06bc Mon Sep 17 00:00:00 2001 From: Kazuya Mio Date: Mon, 30 Jan 2012 17:41:25 +0900 Subject: ext3: Don't call dquot_free_block() if we don't update anything dquot_free_block() is called in the end of ext3_new_blocks() and updates information of the inode structure. However, this update is not necessary if the number of blocks we requested is equal to the number of allocated blocks.
