Title
RDMA/irdma: Fix memory leak of PBLE objects
Summary
In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Fix memory leak of PBLE objects On rmmod of irdma, the PBLE object memory is not being freed. PBLE object memory are not statically pre-allocated at function initialization time unlike other HMC objects. PBLEs objects and the Segment Descriptors (SD) for it can be dynamically allocated during scale up and SD's remain allocated till function deinitialization. Fix this leak by adding IRDMA_HMC_IW_PBLE to the iw_hmc_obj_types[] table and skip pbles in irdma_create_hmc_obj but not in irdma_del_hmc_objects().
