From 5ffc0cb308f69cea36058d308d911f26ee59316e Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 28 Feb 2011 17:04:01 +0530 Subject: fs/9p: Add inode hashing We didn't add the inode to inode hash in 9p. We need to do that to get sync to work, otherwise __mark_inode_dirty will not add the inode to super block's dirty list.
