[PATCH 1/2] mm/page_owner: Rename proc-prefixed variables for clarity

From: Hu Song

Date: Tue Sep 30 2025 - 05:22:14 EST


From: Song Hu <husong@xxxxxxxxxx>

The `proc_page_owner_operations` and related variables were renamed to
`page_owner_fops` to better reflect their association with `debugfs` rather
than `/proc`. This improves code clarity and aligns with kernel naming
conventions.
