    xfs: Fix quota type in quota structures when reusing quota file · dfcc70a8
    Jan Kara authored
    For filesystems without separate project quota inode field in the
    superblock we just reuse project quota file for group quotas (and vice
    versa) if project quota file is allocated and we need group quota file.
    When we reuse the file, quota structures on disk suddenly have wrong
    type stored in d_flags though. Nobody really cares about this (although
    structure type reported to userspace was wrong as well) except
    that after commit 14bf61ff (quota: Switch ->get_dqblk() and
    ->set_dqblk() to use bytes as space units) assertion in
    xfs_qm_scall_getquota() started to trigger on xfs/106 test (apparently I
    was testing without XFS_DEBUG so I didn't notice when submitting the
    above commit).
    
    Fix the problem by properly resetting ddq->d_flags when running quotacheck
    for a quota file.
