From a1d0747a393a079631130d61faa2a61027d1c789 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 11 Aug 2020 18:35:49 -0700 Subject: nilfs2: use a more common logging style Add macros for nilfs_(sb, fmt, ...) and convert the uses of 'nilfs_msg(sb, KERN_, ...)' to 'nilfs_(sb, ...)' so nilfs2 uses a logging style more like the typical kernel logging style.
