Return stat info from read-child in all the inode-write ops
Also modifies the inode-write ops to wait for the call to read-child to return (whether success or failure) before unwinding. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 125 (stat information not returned from the same subvolume always) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=125
