Subject: hpfs: dont call notify_change
From: Miklos Szeredi <mszeredi@xxxxxxx>
hpfs_unlink() calls notify_change() to truncate the file before
deleting. Replace with explicit call to hpfs_notify_change().
This is equivalent, except that:
- security_inode_setattr() is not called before hpfs_notify_change()
- fsnotify_change() is not called after hpfs_notify_change()
The truncation is just an implementation detail, so both the security
check and the notification are unnecessary.
Possibly even the ctime modification is wrong?
