[PATCH RFC -next 01/12] fs: pass struct path to notify_change()
Cai Xinchen
caixinchen1 at huawei.com
Thu Sep 24 10:48:20 UTC 2026
notify_change() takes a struct mnt_idmap and a struct dentry even
though all of its callers either already hold a struct path (or a
struct file) or have to pass &nop_mnt_idmap because no idmapped
mount is involved. Switch the helper and its declaration to take a
struct path instead and derive the idmap and dentry from it.
This is a purely mechanical change with no behavior change. The
security_inode_setattr() call within notify_change() keeps taking
the idmap and dentry for now; it will be converted together with
the LSM hook itself in a separate patch.
Assisted-by: opencode: glm-5.3
