From 4fa76319cd0cc97ca54ff71c94814dc5b1983ad2 Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Tue, 11 Nov 2025 09:12:48 -0500 Subject: vfs: allow rmdir to wait for delegation break on parent In order to add directory delegation support, we need to break delegations on the parent whenever there is going to be a change in the directory. Add a delegated_inode struct to vfs_rmdir() and populate that pointer with the parent inode if it's non-NULL. Most existing in-kernel callers pass in a NULL pointer.
