From 870248428b7fba5540852e784277b7ad00df1452 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 [ Upstream commit 8bd003aca5aa2b1c4ffad18e4986f6cc490e64e5 ] 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.
