From e082f56313f374d723b0366978ddb062c8fe79ea Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Fri, 27 Feb 2015 16:24:28 +0800 Subject: btrfs: quota: Update quota tree after qgroup relationship change. Previous patch modified the in memory struct but it's not written in quota tree until next commit. So user will still get old data using "btrfs qgroup show" after assign/remove. This patch will call btrfs_run_qgroups in assign ioctl so it will be updated to in memory quota trees and user will get up-to-date results.
