quota: fix a problem about transfer quota
Run below script as root, dquot_add_space will return -EDQUOT since __dquot_transfer call dquot_add_space with flags=0, and dquot_add_space think it's a preallocation. Fix it by set flags as DQUOT_SPACE_WARN. mkfs.ext4 -O quota,project /dev/vdb mount -o prjquota /dev/vdb /mnt setquota -P 23 1 1 0 0 /dev/vdb dd if=/dev/zero of=/mnt/test-file bs=4K count=1 chattr -p 23 test-file Fixes: 7b9ca4c61bc2 ("quota: Reduce contention on dq_data_lock") Signed-off-by: yangerkun <yangerkun@huawei.com> Signed-off-by: Jan Kara <jack@suse.cz>
