Using an int value is causing qg->reserved to become negative and
exclusive -EDQUOT to be reached prematurely.
This affects exclusive qgroups only.
TEST CASE:
DEVICE=/dev/vdb
MOUNTPOINT=/mnt
SUBVOL=$MOUNTPOINT/tmp
umount $SUBVOL
umount $MOUNTPOINT
mkfs.btrfs -f $DEVICE
mount /dev/vdb $MOUNTPOINT
btrfs quota enable $MOUNTPOINT
btrfs subvol create $SUBVOL
umount $MOUNTPOINT
mount /dev/vdb $MOUNTPOINT
mount -o subvol=tmp $DEVICE $SUBVOL
btrfs qgroup limit -e 3G $SUBVOL
btrfs quota rescan /mnt -w
for i in `seq 1 44000`; do
dd if=/dev/zero of=/mnt/tmp/test_$i bs=10k count=1
if [[ $? > 0 ]]; then
btrfs qgroup show -pcref $SUBVOL
exit 1
fi
done

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
