List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Amir Shehata , Lustre Development List MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: lustre-devel-bounces@lists.lustre.org Sender: "lustre-devel" From: Sonia Sharma The ioctl handler for "add policy" de-marshals the udsp rules passed from userspace and then add the rules if there is no copy of the same rules already added. Apply the rules to the existing LNet constructs.
