generic/019 reports below error:
__quota_error: 1160 callbacks suppressed Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota VFS: Busy inodes after unmount of zram1. Self-destruct in 5 seconds. Have a nice day...
If we failed in below path due to fail to write dquot block, we will miss to release quota inode, fix it.
- f2fs_put_super - f2fs_quota_off_umount - f2fs_quota_off - f2fs_quota_sync <-- failed - dquot_quota_off <-- missed to call
