commit: 7d8f98769e7f4bc29c38789daeb416c6a7d7c241 From: Tao Ma <[email protected]> Date: Wed, 22 Dec 2010 17:50:30 +0800 Subject: [PATCH] ocfs2: Fix system inodes cache overflow.
When we store system inodes cache in ocfs2_super, we use a array for global system inodes. But unfortunately, the range is calculated wrongly which makes it overflow and pollute ocfs2_super->local_system_inodes. This patch fix it by setting the range properly. The corresponding bug is ossbug1303. http://oss.oracle.com/bugzilla/show_bug.cgi?id=1303 Cc: [email protected] Signed-off-by: Tao Ma <[email protected]> Signed-off-by: Joel Becker <[email protected]> --- fs/ocfs2/ocfs2_fs.h | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/fs/ocfs2/ocfs2_fs.h b/fs/ocfs2/ocfs2_fs.h index c2e4f82..bf2e776 100644 --- a/fs/ocfs2/ocfs2_fs.h +++ b/fs/ocfs2/ocfs2_fs.h @@ -350,7 +350,7 @@ enum { #define OCFS2_LAST_LOCAL_SYSTEM_INODE LOCAL_GROUP_QUOTA_SYSTEM_INODE NUM_SYSTEM_INODES }; -#define NUM_GLOBAL_SYSTEM_INODES OCFS2_LAST_GLOBAL_SYSTEM_INODE +#define NUM_GLOBAL_SYSTEM_INODES OCFS2_FIRST_LOCAL_SYSTEM_INODE #define NUM_LOCAL_SYSTEM_INODES \ (NUM_SYSTEM_INODES - OCFS2_FIRST_LOCAL_SYSTEM_INODE) _______________________________________________ stable mailing list [email protected] http://linux.kernel.org/mailman/listinfo/stable
