Userobj, groupobj and project quotas
This includes the commit:
Add types to featureflags in zfs
as well as commits for userobj quotas, and project quotas, all in one PR.
They are rather intertwined.
This is a port from HEAD on ZOL master today - not the original commits (plus updates). Some git history is lost.
Userobj, and Groupobj quotas appear to work:
tank feature@userobj_accounting active local
tank feature@project_quota active local
# zfs set userobjquota@lundman=100 tank
# zfs get userobjquota@lundman tank
NAME PROPERTY VALUE SOURCE
tank userobjquota@lundman 100 local
# for i in {1..200}; do touch /Volumes/tank/file$i; done
touch: /Volumes/tank/file101: Disc quota exceeded
# zfs get userobjused@lundman tank
NAME PROPERTY VALUE SOURCE
tank userobjused@lundman 50K local
(Why is it 50k?! I expect to see 100 - possibly bug in zfs_main.c - research)
# zfs set groupobjquota@staff=100 tank
# zfs get groupobjquota@staff tank
NAME PROPERTY VALUE SOURCE
tank groupobjquota@staff 100 local
-
Further testing of userobj, and groupobj quotas required.
-
Further testing with project quotas required.
- The use of
zfs set|get project*quota | project*usedshould at least work. zfs projectcommand should run, but we expectInappropriate ioctl for deviceas there are no Projects in XNU.
Ah hmm it seems the ret = ioctl(fd, ZFS_IOC_FSGETXATTR, &fsx); is an internal ioctl, so doesn't involve some feature of Linux kernel, and should be implemented.

"should be implenented" - is this ready for testing then or should it be implenented first before it gets to testing?
I haven't tested much new functionality of this PR, I just use this branch with my ZFS pool created with current ZoL 0.8.4 without any features disabled by command from OpenZFS wiki on Debian root on ZFS :
zpool create \
-o ashift=12 \
-O acltype=posixacl -O canmount=off -O compression=lz4 \
-O dnodesize=auto -O normalization=formD -O relatime=on \
-O xattr=sa -O mountpoint=/ -R /mnt \
rpool ${DISK}-part4
I saw two freezes today when I try to zfs destroy -r <dataset>. This dataset is created from macOS and don't have any features of this PR enabled. Here is its properties:

It contains only clone of opengapps repo in a subfolder and has mds disabled by file .metadata_never_index and removing corresponding mds directory. That's all I can say about it. I haven't found any mention of zfs in my standard macOS logs GUI.
Oh sorry, not resets, but complete freezes, so GUI is there, but no clock ticks (I have seconds enabled in my clock).
