Currently f_fsid of struct kstatfs returned from ocfs2_statfs() is undefined (vfs layer fills 0 as default). Since in some conditions, f_fsid value might be used as (f_fsid, ino) pair to uniquely identify a file, ocfs2 should return a unique defined f_fsid value from ocfs2_statfs(). Because uuid_str is identified no mater on big or litlle endian machine, it's also endian consistent to use osb->uuid_str to generate f_fsid value.

This patch series adds support for preservation of the VM generation ID buffer address in xenstore across save/restore and migrate, and also code to increment the value in all cases except for migration. Patch 1 modifies the guest ro and rw node creation to an open coding style and cleans up some extraneous node creation. Patch 2 modifies creation of the hvmloader key in xenstore and adds

Currently f_fsid of struct kstatfs returned from ocfs2_statfs() is undefined (at least it should be filled with 0). Since in some conditions, f_fsid value might be used as (f_fsid, ino) pare to uniquely identify a file, ocfs2 should return a defined unique f_fsid value from ocfs2_statfs(). This patch uses uuid_hash as a unique ID to initiate f_fsid value, the 32bits width is enough for ocfs2

Hi, All, These four patches are all related to ocfs2 on hard readonly mount. patch 1 fix oops when umount ocfs2 on hard readonly device. Because ocfs2_dismount_volume() will call ocfs2_cluster_hangup() and then call ocfs2_stack_driver_put(), will hit BUG_ON(active_stack == NULL). patch 2 fix oops when do ls or cat in ocfs2 on hard readonly device. Because ocfs2_open_lock() will call

Now it's a good time to introduce the new tool 'o2info' since kernel part of OCFS2_IOC_INFO ioctl has been pulld upstream by linus. The following 6 patches have already got sunil's SOBs, and now they're trying to attract more reviewers before it goes to central repo with a modification of getting manual pages being introduced.

From: Anand <anand.jain@oracle.com> This patch adds creation-time to the snapshot list display, which would help user to better manage the snapshots when number of snapshots grow substantially.

The following series of patches comprises the bulk of our outstanding changes for Ocfs2. Aside from the usual set of cleanups and fixes that were inappropriate for 2.6.25, there are a few highlights: The '/sys/o2cb' directory has been moved to '/sys/fs/o2cb'. The new location meshes better with modern sysfs layout. A symbolic link has been placed in the old location so as to
