Subject: ftrace: Add add_ftrace_hash_entry function
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2cd298c106e00ba1d8799b022594f131703f32fa;p=thirdparty%2Flinux.git

ftrace: Add add_ftrace_hash_entry function

Renaming __add_hash_entry to add_ftrace_hash_entry and making it global,
it will be used in following changes outside ftrace.c object.
