[PATCH] alpha: osf_sys: reduce kernel log spamming on invalid osf_mount call typenr

From: Colin Ian King
Date: Mon Dec 13 2021 - 13:56:31 EST


Calling the osf_mount system call with an invalid typenr value will
spam the kernel log with error messages. Reduce the spamming by making
it a ratelimited printk. Issue found when exercising with the stress-ng
enosys system call stressor.
