Subject: [PATCH] Branch b1_8_gate b=16362 i=bzzz i=adilger

looking up an inode via iopen with the wrong generation number can
populate the dcache with a disconneced dentry while the inode
number is in the process of being reallocated. This causes an
assertion failure in iopen since the inode's dentry list contains
both a connected and disconnected dentry.
