Linux kernel source tree
60bd24f272
DAMON sysfs interface tests if given online parameters update request is valid, by committing those using the DAMON kernel API, to a test-purpose destination context. The test-purpose destination context is constructed using damon_new_ctx(), so it has no target, no scheme. If a source target has the obsolete field set, the test-purpose commit will fail because damon_commit_targets() fails when there is a source obsolete target that cannot find its matching destination target. DAMON sysfs interface is not letting users set the field for now, so there is no problem. However, the following commit will support that. Also there could be similar future changes that making commit fails based on current context structure. Make the test purpose commit destination context similar to the current running one, by committing the running one to the test purpose context, before doing the real test-purpose commit.

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.
