Currently, the CSD-lock diagnostics in CONFIG_CSD_LOCK_WAIT_DEBUG=y kernels are emitted at five-second intervals. Although this has proven to be a good time interval for the first diagnostic, if the target CPU keeps interrupts disabled for way longer than five seconds, the ratio of useful new information to pointless repetition increases considerably. Therefore, back off the time period for repeated reports of the same incident, increasing linearly with the number of reports and logarithmicly with the number of online CPUs.

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.
