From b248eaf049d9cdc5eb76b59399e4d3de233f02ac Mon Sep 17 00:00:00 2001 From: Zhihao Cheng Date: Tue, 11 Oct 2022 11:47:30 +0800 Subject: [PATCH] ubifs: Fix wrong dirty space budget for dirty inode Each dirty inode should reserve 'c->bi.inode_budget' bytes in space budget calculation. Currently, space budget for dirty inode reports more space than what UBIFS actually needs to write.
