Linux kernel source tree
8e1817b6ba
There have been no reported infinite loops in the tree, but checking the detection of an infinite loop during validation is simple enough. Add the detection to the validate_mm() function so that error reports are clear and don't just report stalls. This does not protect against internal maple tree issues, but it does detect too many vmas being returned from the tree. The variance of +10 is to allow for the debugging output to be more useful for nearly correct counts. In the event of more than 10 over the map_count, the count will be set to -1 for easier identification of a potential infinite loop. Note that the mmap lock is held to ensure a consistent tree state during the validation process.

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.
