Subject: [PATCH 4.19 22/30] scsi: target/core: Use kmem_cache_free() instead of kfree()

4.19-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <weiyongjun1@...wei.com>

commit 8b2db98e814a5ec45e8800fc22ca9000ae0a517b upstream.

memory allocated by kmem_cache_alloc() should be freed using
kmem_cache_free(), not kfree().

Fixes: ad669505c4e9 ("scsi: target/core: Make sure that target_wait_for_sess_cmds() waits long enough")
