Subject: [PATCH v2 04/33] ibmvfc: free ibmvfc_target allocations with mempool_free
Date: Wed, 22 Jul 2026 17:01:20 -0700 [thread overview]
Message-ID: <20260723000149.969416-5-tyreld@linux.ibm.com> (raw)
In-Reply-To: <20260723000149.969416-1-tyreld@linux.ibm.com>
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.
