[Ocfs2-tools-devel] [PATCH 0/7] Ocfs2-tools: Add new tool[o2info] to ocfs2-tools: V1.

[Tristan]

V1 version is a very much preliminary implementation, It fulfill 2 
options from design doc.

1. --volfino
2. --fs-features

It used newly-added ioctls in ocfs2 to gather filesys info from 
none-privileged end-user in a mounted case,
while it also support super user to use libocfs2 to access the same 
info, as in,

#o2info --fs-features /dev/sdax

#o2info --fs-features /storage

Above 2 methods dump the same info we requested.

I posted the patches to get it reviewed early though only 2 options get 
finished.


Regards,
Tristan.
