Subject: xprtrdma: Fix regbuf data not freed in rpcrdma_req_create()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=17c49afc694eb3ab4e1b56e41cb186c3ad77a2ed;p=users%2Fjedix%2Flinux-maple.git

xprtrdma: Fix regbuf data not freed in rpcrdma_req_create()

[ Upstream commit 9181f40fb2952fd59ecb75e7158620c9c669eee3 ]

If rdma receive buffer allocate failed, should call rpcrdma_regbuf_free()
to free the send buffer, otherwise, the buffer data will be leaked.
