Cut off the version suffix (e.g. @GLIBC_2.2.5 etc.) from automatic
generated event name. This fixes wildcard event adding like below case;
=====
# perf probe -x /lib64/libc-2.25.so malloc*
Internal error: "malloc_get_state@GLIBC_2" is wrong event name.
Error: Failed to add events.
=====
This failure was caused by a versioned suffix symbol.
With this fix, perf probe automatically cuts the suffix after @ as
below.
=====
# ./perf probe -x /lib64/libc-2.25.so malloc*
Added new events:
probe_libc:malloc_printerr (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_consolidate (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_check (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_hook_ini (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_trim (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_usable_size (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_stats (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_info (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:mallochook (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_get_state (on malloc* in /usr/lib64/libc-2.25.so)
probe_libc:malloc_set_state (on malloc* in /usr/lib64/libc-2.25.so)
You can now use it in all perf tools, such as:
perf record -e probe_libc:malloc_set_state -aR sleep 1

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.
