Bug 216256

Hello,

EIO is returned instead of EDQUOT, especially using fusefs-encfs.
I'm not sure it is related to encfs, but perhaps more to fuse or to kernel.

Example :

# zfs create home/test
# zfs set userquota@root=1G home/test
# dd if=/dev/zero of=/home/test/toobig bs=128k
dd: /home/test/toobig: Disc quota exceeded
# rm /home/test/toobig 

# mkdir /home/test/one
# mkdir /home/test/two
# echo "p
password" | encfs -S /home/test/one/ /home/test/two/
# mount | grep fuse
/dev/fuse on /home/test/two (fusefs, local, synchronous)
# dd if=/dev/zero of=/home/test/two/toobig bs=128k
dd: /home/test/two/toobig: Input/output error

dd, writing to fuse, should have returned EDQUOT instead of EIO.

I've found something quite similar under RHEL :

Thank you !
