commit7b1ae24827upstream. Query like 'file tcp_input.c line 1234 +p' was broken by commitaaebe329bf("dyndbg: accept 'file foo.c:func1' and 'file foo.c:10-100'") because a file name without a ':' now makes the loop in ddebug_parse_query() exits early before parsing the 'line 1234' part. As a result, all pr_debug() in tcp_input.c will be enabled, instead of only the one on line 1234. Changing 'break' to 'continue' fixes this.

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.
