From eb782652045e67a5379dd319613b0d3d924901dd Mon Sep 17 00:00:00 2001 From: "Luis Henriques (SUSE)" Date: Fri, 5 Apr 2024 15:24:02 +0100 Subject: [PATCH] e2fsck: update quota accounting after directory optimization In "Pass 3A: Optimizing directories", a directory may have it's size reduced. If that happens and quota is enabled in the filesystem, the quota information will be incorrect because it doesn't take the rehash into account. This issue was detected by running fstest ext4/014. This patch simply updates the quota data accordingly, after the directory is written and it's size has been updated.
