From 23cf7212a1cae2158dcf5f41d9733d59e320f8f6 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Wed, 15 Feb 2017 10:34:45 +0800 Subject: [PATCH] f2fs: introduce noinline_xattr mount option This patch introduces new mount option 'noinline_xattr', so we can disable inline xattr functionality which is already set as a default mount option.
