commit 66072c29328717072fd84aaff3e070e3f008ba77 upstream. syzbot is reporting ODEBUG messages at hfsplus_fill_super() [1]. This is because hfsplus_fill_super() forgot to call cancel_delayed_work_sync(). As far as I can see, it is hfsplus_mark_mdb_dirty() from hfsplus_new_inode() in hfsplus_fill_super() that calls queue_delayed_work(). Therefore, I assume that hfsplus_new_inode() does not fail if queue_delayed_work() was called, and the out_put_hidden_dir label is the appropriate location to call cancel_delayed_work_sync().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
