Subject: SUNRPC: Never reuse the socket port after an xs_close()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=246408dcd5dfeef2df437ccb0ef4d6ee87805f58;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

SUNRPC: Never reuse the socket port after an xs_close()

If we call xs_close(), we're in one of two situations:
 - Autoclose, which means we don't expect to resend a request
 - bind+connect failed, which probably means the port is in use
