Quoting Sudhir Kumar (sku...@linux.vnet.ibm.com): > This patch changes the way information is exchanged between parent and child. > This is required because of the following reason: > Earlier the child was in the same pid namespace as parent and this info was > passed from the child to the parent through a fifo. But now the child is in > a separate pid namespace and hence this pid will not make any sence to the > parent. > > Signed-off-by: Sudhir Kumar <sku...@linux.vnet.ibm.com>
