Where did the owner field of the proc_dir_entry structure go? [Linux kernel]

Question

According to the list of API changes in the 2.6 kernel series, the LWN field .owner struct proc_dir_entrywas deleted at 2.6.30 The kernel.

So here are a couple of questions:

• Was it really necessary or useful to set this field?
• Has the field been moved elsewhere or permanently deleted?

I ask the first question, because while LKMPG sets this field in many examples , procfs_example.c from the kernel documentation never does.

I'm not an expert on the Linux kernel, but maybe this entry has some meaning for you:
