commit 7d01cb27f6aebc54efbe28d8961a973b8f795b13 upstream. This reverts commit 122deabfe1428 (ubifs: dirty_cow_znode: Fix memleak in error handling path). After commit 122deabfe1428 applied, if insert_old_idx() failed, old index neither exists in TNC nor in old-index tree. Which means that old index node could be overwritten in layout_leb_in_gaps(), then ubifs image will be corrupted in power-cut.

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.
