v2->v3:
fix the comment to mention that strncpy_from_unsafe() returns
the length of the string including the trailing NUL.

v1->v2:
patch 1: generalize FETCH_FUNC_NAME(memory, string) into
strncpy_from_unsafe()
patch 2: use it in bpf_trace_printk

Alexei Starovoitov (2):
  lib: introduce strncpy_from_unsafe()
  bpf: add support for %s specifier to bpf_trace_printk()
