Richard Weinberger 6a45b3628c ovl: Fix info leak in ovl_lookup_temp() ... The function uses the memory address of a struct dentry as unique id. While the address-based directory entry is only visible to root it is IMHO still worth fixing since the temporary name does not have to be a kernel address. It can be any unique number. Replace it by an atomic integer which is allowed to wrap around.
