Subject: igrab() should check for I_CLEAR
From: Jan Blunck <jblunck@xxxxxxx>
When igrab() is calling __iget() on an inode it should check if
clear_inode() has been called on the inode already. Otherwise there is a
race window between clear_inode() and destroy_inode() where igrab() calls
__iget() which leads to already free inodes on the inode lists.
