[PATCH 5/5] perf trace: Add beautifier for clock_gettime's clk_id argument - v2

[David Ahern]

Before:
0.030 ( 0.002 ms): 2571 clock_gettime(which_clock: 1, tp: 0x7f3b45729cd0 ) = 0

After:
0.030 ( 0.002 ms): 2571 clock_gettime(which_clock: MONOTONIC, tp: 0x7f3b45729cd0 ) = 0

v2: Update to use the STRARRAY option
