Subject: [PATCH] cifs: make fs_context error logging wrapper
Git-commit: 9d4ac8b6302c60a1949560e501fc1d0b4654b9c6
Patch-mainline: v5.13-rc1
References: bsc#1192606
This new helper will be used in the fs_context mount option parsing
code. It log errors both in:
* the fs_context log queue for userspace to read
* kernel printk buffer (dmesg, old behaviour)
