btrfs: quota: Update quota tree after qgroup relationship change.

e082f563 · Qu Wenruo <[email protected]> · 2015-02-27 16:24:28 +08:00

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.
