Subject: [v3 0/5] Add project quota support for e2fsprogs

The following patches adds project quota support for e2fsprogs. The
first patch cleans up current codes to prepare for adding project
quota support. And other patches adds project ID as well as project
feature support for e2fsprogs.

Li Xi (5):
Clean up codes for adding new quota type
Add project feature flag EXT4_FEATURE_RO_COMPAT_PROJECT
Add project quota support
Add inherit flags for project quota
Add project ID support for chattr/lsattr

Subject: [v3 1/5] Clean up codes for adding new quota type

Project quota related fields are reserved in Linux kernel.
As a preparation for it, this patch cleans up quota codes
of e2fsprogs so as to make it easier to add new quota type(s).

Subject: [v3 4/5] Add inherit flags for project quota

This patch add EXT4_PROJINHERIT_FL to enable inherit feature for
project ID. If an directory has its inherit flag set, all its
newly created children will inherit its project ID. Conversely,
new inodes will get a default project ID (i.e. zero). Also, no
hard link or rename is permitted if the directory and child has
different project ID.

Subject: [v3 2/5] Add project feature flag EXT4_FEATURE_RO_COMPAT_PROJECT

This patch add project feature flag EXT4_FEATURE_RO_COMPAT_PROJECT.
Project feature is a read-only compat feature. Thus, an ext4 file
system with project feature enabled could only be read by ext4
kernel module without project feature support.

Subject: [v3 3/5] Add project quota support

This patch adds project quota support. An new quota type PRJQUOTA(2)
is added. EXT4_PRJ_QUOTA_INO(11) is reserved for project quota inode.
The super block reservers an field s_prj_quota_inum for saving
project quota inode. And each inode adds an internal field i_projid
for saving its project ID.

Hi, this patch is missing the new files for fgetproject.c and
fsetproject.c. Can you resend them, please?

Hi Teb, sorry for my late reply.

We are improving the patches internally. But it was on a different branch.
And I am rebasing it to master branch. I will push the patch series again
in a few hours.

Li Xi
