When we derive event names, convert some expected symbols (such as ':'
used to specify module:name and '.' present in some symbols) into
underscores so that the event name is not rejected.
Before this patch:
# echo 'p kobject_example:foo_store' > kprobe_events
trace_kprobe: Failed to allocate trace_probe.(-22)
-sh: write error: Invalid argument
After this patch:
# echo 'p kobject_example:foo_store' > kprobe_events
# cat kprobe_events
p:kprobes/p_kobject_example_foo_store_0 kobject_example:foo_store

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
