From d344b0fb72e00339625464c5a29711906fa70b8b Mon Sep 17 00:00:00 2001 From: "Venkateswararao Jujjuri (JV)" Date: Thu, 13 Jan 2011 16:33:00 -0800 Subject: [fs/9p] Initialze cached acls both in cached/uncached mode. With create/mkdir/mknod in non cached mode we initialize the inode using v9fs_get_inode. v9fs_get_inode doesn't initialize the cache inode value to NULL. This is causing to trip on BUG_ON in v9fs_get_cached_acl. Fix is to initialize acls to NULL and not to leave them in ACL_NOT_CACHED state.
