write-truncate-chown: test delalloc + quota_transfer
I've written crappy quotactl for quota manipulation
(which i use for ct-tree-quota development).Some times
it more useful. See files attached.

mkfs.ext4 /dev/sdb5 -b4096
mount /dev/sdb5 /mnt -ogrpquota,usrquota
quotacheck -cug /mnt
# sync is necessary, because files may have reserved some blocks
# which later lead to complain from claim_reserved_space
# Probably we have print *huge* warning if we found
# file with reserved blocks inodes traversing on quotaon 
sync;sync;sync
# turn on quota
./quotactl --all --on --device=/dev/sdb5 --path /mnt
# run test
./write-truncate-chown /mnt/ 9999999999&
# get quota report, print warn in case of incorrect quota.
./quotactl --all --get --type 0 --device=/dev/sdb5 || echo "failed"
# checkout dmesg
dmesg
