This reverts commitcc798c8389. Tony writes: Somehow this causes a regression in Linux next for me where I'm seeing lots of sysfs entries now missing under /sys/bus/platform/devices. For example, I now only see one .serial entry show up in sysfs. Things work again if I revert commitcc798c8389("kernfs: fix memleak inkernel_ops_readdir()"). Any ideas why that would be? Tejun says: Ugh, you're right. It can get double-put cuz ctx->pos is put by release too. So reverting it for now.

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.
