Subject: [PATCH] fs/quota: update quota state flags scheme with project quota flags
Date:   Sun, 18 Oct 2020 05:56:54 +0300
Message-Id: <1602989814-28922-1-git-send-email-dotdot@yandex-team.ru>
Precedence: bulk

Current quota state flags scheme doesn't include project quota and thus
shows all flags after DQUOT_USAGE_ENABLED wrong. Fix this and also add
DQUOT_NOLIST_DIRTY to the scheme.
