From 19c4b380f23e5a445cfc9e922c996784990d218c Mon Sep 17 00:00:00 2001 From: Hongbo Li Date: Thu, 10 Jul 2025 12:14:11 +0000 Subject: [PATCH] f2fs: Allow sbi to be NULL in f2fs_printk At the parsing phase of the new mount api, sbi will not be available. So here allows sbi to be NULL in f2fs log helpers and use that in handle_mount_opt().
