[LU-15969] new project VFS interface ->fileattr_get for PCC project quota

• Status: Reopened
• Project: Lustre
• Fix Version/s: Lustre 2.16.0
• Type: Bug
• Priority: Minor
• Reporter: Qian Yingjin
• Assignee: Qian Yingjin
• Resolution: Unresolved
• Severity: 3

Description

The new Ubuntu 2204 kernel introduces a new project set/get VFS interface ->fileattr_get() and ->fileattr_set().
In PCC, we set the project ID for PCC copies on PCC backend device via FS_IOC_FSSETXATTR:

old_fs = force_uaccess_begin();
        rc = file->f_op->unlocked_ioctl(file, FS_IOC_FSSETXATTR,
                                        (unsigned long)&fsx);
force_uaccess_end(old_fs);

However, the new kernel removes this project IOCTL, this result in the ioctl returns -ENOTTY.
and result in the sanity-pcc test_39 failed.

We need to add compatibility check for this new project VFS interface, and fix the setting for PCC project ID properly.
