From: Leo Yan
Date: Wed Apr 18 2018 - 21:34:28 EST

This patch series is minor fixes and cleanup for bpf load and samples
code. The first one patch is typo fixing; patch 0002 is refactor for
dynamically allocate memory for kernel symbol structures; the last
three patches are mainly related with refactor with function
ksym_search(), the main benefit of this refactor is program sampleip
can be used without architecture dependency.

The patch series has been tested on ARM64 Hikey960 boards.

Leo Yan (5):
samples/bpf: Fix typo in comment
samples/bpf: Dynamically allocate structure 'syms'
samples/bpf: Use NULL for failed to find symbol
samples/bpf: Refine printing symbol for sampleip
samples/bpf: Handle NULL pointer returned by ksym_search()
