If anyone has any objections, please let me know. ------------------ From: Tyrel Datwyler [ Upstream commit 99143433f7f14139ac373c553ec8e1317d0ae58a ] The ibmvfc_target *tgt structures for discovery are allocated using mempool_alloc but in turn free'd via kfree in ibmvfc_release_target breaking pool guarentees. Fixup ibmvfc_release_target to call mempool_free instead so that memory is properly returned to the mempool instead of the general allocator.
