SeongJae Park 8debfc5b1a mm/damon/core: fix new damon_target objects leaks on damon_commit_targets()
Patch series "mm/damon/core: fix memory leaks and ignored inputs from
damon_commit_ctx()".

Due to two bugs in damon_commit_targets() and damon_commit_schemes(),
which are called from damon_commit_ctx(), some user inputs can be ignored,
and some mmeory objects can be leaked.  Fix those.

Note that only DAMON sysfs interface users are affected.  Other DAMON core
API user modules that more focused more on simple and dedicated production
usages, including DAMON_RECLAIM and DAMON_LRU_SORT are not using the buggy
function in the way, so not affected.


This patch (of 2):

When new DAMON targets are added via damon_commit_targets(), the newly
created targets are not deallocated when updating the internal data
(damon_commit_target()) is failed.  Worse yet, even if the setup is
successfully done, the new target is not linked to the context.  Hence,
the new targets are always leaked regardless of the internal data setup
failure.  Fix the leaks.

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.
