* libglusterfsclient: Dont alloc root inode contextShehjar Tikoo2009-11-031-1/+0
| | | | | | | | | | | | ....because the lookup on root inode done a few lines before this call already allocates an inode context. This one just over-writes that context, results in invalidation of the cached iattrs. Signed-off-by: Shehjar Tikoo <shehjart@gluster.com> Signed-off-by: Anand V.
