Dynamic reconfiguration of queue pairs in a data processing system is provided. A device driver determines whether a dynamic CPU reconfiguration has added one or more CPUs to the data processing system, wherein the data processing system comprises a number of CPUs and a number of queue pairs. Responsive to the dynamic CPU configuration adding one or more CPUs, the device driver allocates a portion of a memory corresponding to a queue pair, wherein each queue pair comprises a receive queue and a transmit queue, programs a receive side scaling mechanism in a network adapter to allow for dynamic insertion of a processing engine associated with the queue pair, and enables transmit tuple hashing to the queue pair.

A method for determining whether a soft link of a target file is pointing to a correct file system is provided. A unique identification number for a mounted file system is retrieved from a storage device in response to receiving a request to access a target file in the mounted file system. In addition, an identification number is retrieved from a soft link of the target file in response to accessing the soft link of the target file in the storage device. Then, it is determined whether a match exists between the unique identification number for the mounted file system and the identification number from the soft link of the target file. In response to determining that a match does exist between the unique identification number for the mounted file system and the identification number from the soft link of the target file, access to the target file is allowed.
