Al Viro 29dfeb0b6a hypfs: don't bother with d_delete()
If that's not the last reference, d_delete() will do d_drop().
If it is, dput() immediately after it will unhash the sucker
anyway, since ->d_delete() the method is always_delete_dentry().

IOW, there's no point trying to turn it into a negative hashed
dentry - it won't stick around anyway.  Just d_drop() it and be
done with that.

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 Restructured Text 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.
