From 67510d7e2e5f5bdc020bf9d759aa575cce48c8e1 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 10 Jan 2025 08:58:14 +0100 Subject: fs: debugfs: fix open proxy for unsafe files In the previous commit referenced below, I had to split the short fops handling into different proxy fops. This necessitated knowing out-of-band whether or not the ops are short or full, when attempting to convert from fops to allocated fsdata. Unfortunately, I only converted full_proxy_open() which is used for the new full_proxy_open_regular() and full_proxy_open_short(), but forgot about the call in open_proxy_open(), used for debugfs_create_file_unsafe(). Fix that, it never has short fops.
