Fix bug of the extra newline characters in debugfs logs. When a line is added to debugfs with a newline character at the end, an extra line appears in the debugfs log. This is due to a discrepancy between how the lines are printed and how they are added to the logs. Remove this discrepancy by checking if a newline character is present before adding a newline character. This should closely match the printk behavior. Add kunit_log_newline_test to provide test coverage for this issue. (Also, move kunit_log_test above suite definition to remove the unnecessary declaration prior to the suite definition) As an example, say we add these two lines to the log: kunit_log(..., "KTAP version 1\n"); kunit_log(..., "1..1"); The debugfs log before this fix: KTAP version 1 1..1 The debugfs log after this fix: KTAP version 1 1..1 Signed-off-by: Rae Moar <rmoar@google.com> Reviewed-by: David Gow <davidgow@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>
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 Restructured Text 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.
