  "message": "kallsyms: Do not display SyS_foo() syscall aliases in kallsyms\n\nThe SyS_foo() alias wrapper was added to make sure that system call\narguments were signed extended. The call itself is to never be used\nby anything, only the sys_foo() version is. But this symbol is stored\nin /proc/kallsyms, and is returned sometimes as the name of system\ncall functions when a ksym lookup is made, it confuses the function\ntracer interface (see available_filter_functions in the tracefs\ndirectory).\n\nAl Viro even suggested that this should be removed from kallsyms\nas well:\n\nLink: http://lkml.kernel.org/r/20130510211716.GN25399@ZenIV.linux.org.uk\n\nModify the compile time kallsyms.c to check if the function name\nbegins with SyS_ and is before or after the same name that starts\nwith sys_ and if so, do not record it. This saves some space and\nmore importantly removes the confusing variations of the system\ncall name.\n\n wc kallsyms.*\n  90151  284644 3819255 kallsyms.orig\n  89826  283669 3808628 kallsyms.patched\n\n size vmlinux*\n   text    data     bss     dec     hex filename\n9990933 2368592 1249280 13608805         cfa765 vmlinux.orig\n9986837 2368592 1249280 13604709         cf9765 vmlinux.patched\n\nThis patch only removes SyS_*, it does not do anything with\ncompat_SyS_*.\n\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n",
