Subject: xprtrdma: Squelch ENOBUFS warnings
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0031e47c76ec5ce5b4f64f2750a535a36040c82b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

xprtrdma: Squelch ENOBUFS warnings

When ro_map is out of buffers, that's not a permanent error, so
don't report a problem.
