Guangguan Wang dc25553cc6 net/smc: non blocking recvmsg() return -EAGAIN when no data and signal_pending
[ Upstream commit f3c46e41b32b6266cf60b0985c61748f53bf1c61 ]

Non blocking sendmsg will return -EAGAIN when any signal pending
and no send space left, while non blocking recvmsg return -EINTR
when signal pending and no data received. This may makes confused.
As TCP returns -EAGAIN in the conditions described above. Align the
behavior of smc with TCP.

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
