A mix of persistent and non-persistent dentries in there. Strictly speaking, no need for kill_litter_super() anyway - it pins an internal mount whenever a persistent dentry is created, so at fs shutdown time there won't be any to deal with. However, let's make it explicit - replace d_instantiate() with d_make_persistent() + dput() (the latter in tracefs_end_creating(), where it folds with inode_unlock() into simple_done_creating()) for dentries we want persistent and have d_make_discardable() done either by simple_recursive_removal() (used by tracefs_remove()) or explicitly in eventfs_remove_events_dir().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
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.
