Since the kernel includes many non-global functions with same names, we will need to use offsets from other symbols (typically _text/_stext) or absolute addresses to place return probes on specific functions. Also, the core register_kretprobe() API never forbid use of offsets or absolute addresses with kretprobes. Allow its use with the trace infrastructure. To distinguish kernels that support this, update ftrace README to explicitly call this out. Signed-off-by: Naveen N.

README
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.
