Subject: [PATCH] cifs: fix wrong release in sess_alloc_buffer() failed path
Date: Tue, 17 Aug 2021 22:55:10 +0800	[thread overview]
Message-ID: <20210817145510.639-1-dinghui@sangfor.com.cn> (raw)

smb_buf is allocated by small_smb_init_no_tc(), and buf type is
CIFS_SMALL_BUFFER, so we should use cifs_small_buf_release() to
release it in failed path.
