Description Eugene Teo (Security Response) 2010-08-05 23:23:05 EDT
There is a typo here.  We should be testing "*dentry" which was just assigned instead of "dentry".  This could result in dereferencing an ERR_PTR inside either usbfs_mkdir() or usbfs_create().

Not sure how this slipped by. We have the above commit in our current MRG 2.0 tree since v2.6.33.4-rt21. 

Ok to close with CURRENTRELEASE?
