From 9434fcde1fa0f48e1a29fbdd9d436fa279aeb909 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Tue, 11 Oct 2016 22:57:02 +0800 Subject: [PATCH] f2fs: add missing f2fs_balance_fs in f2fs_zero_range f2fs_balance_fs should be called in between node page updating, otherwise node page count will exceeded far beyond watermark of triggering foreground garbage collection, result in facing high risk of hitting LFS allocation failure.
