From b3cbea03b4edbd6b625dbf813bf8c30c22213cb7 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 28 Feb 2011 17:04:06 +0530 Subject: fs/9p: Add support for marking inode attribute invalid With cached mode some of the file system operation result in updating inode attributes (ctime). Add support for marking inode attribute invalid in such cases so that we fetch the updated inode attribute on dentry revalidation.
