Linux kernel source tree

This was detected at the end of a 'perf record' session when build-id collection was enabled and thus the BPF programs put in place while the session was running, some even put in place by perf itself were processed and inserted, with some overlaps related to BPF trampolines and programs took place. Using maps__fixup_overlap_and_insert() instead of maps__insert() "fixes" the problem, in the sense that overlaps will be dealt with and then the consistency will be kept, but it would be interesting to fully understand why such overlaps take place and how to deal with them when doing symbol resolution.

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.
