static contents for each "service processor", whatever the fuck it is. Congruent subdirectories of root, created at mount time, taken out by kill_litter_super(). All dentries created with d_alloc_name() and are left pinned. The odd part is that the list of service providers is assumed to be unchanging - no locking, nothing to handle removals or extra elements added later on. ... and it's a PCI device. If you ever tell it to remove an instance, you are fucked - it doesn't bother with removing its directory from filesystem, it has a strange check that presumably wanted to be a check for removed devices, but it had never been fleshed out. Anyway, d_add() -> d_make_persistent()+dput() in ibmasmfs_create_dir() and ibmasmfs_create_file(), and make the latter return int - no need to even borrow that dentry, callers completely ignore it.

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.
