Subject: xprtrdma: Fix error code in rpcrdma_buffer_create()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4429b668e0375206408617d6440e3bb76c56c7d2;p=linux.git

xprtrdma: Fix error code in rpcrdma_buffer_create()

This should return -ENOMEM if __alloc_workqueue_key() fails, but it
returns success.

Fixes: 6d2d0ee27c7a ("xprtrdma: Replace rpcrdma_receive_wq with a per-xprt workqueue")
