perf trace beauty futex: Beautify FUTEX_BITSET_MATCH_ANY
E.g.:
# strace -e futex -p 14437
strace: Process 14437 attached
futex(0x7f46f4808d70, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7f46f24e68b0, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 0, {tv_sec=1516636744, tv_nsec=221969000}, 0xffffffff) = -1 ETIMEDOUT (Connection timed out)
<detached ...>
#
Should pretty print that 0xffffffff value, like:
# trace -e futex --tid 14437
0.028 ( 0.005 ms): futex(uaddr: 0x7f46f4808d70, op: WAKE|PRIV, val: 1 ) = 0
0.037 (1000.092 ms): futex(uaddr: 0x7f46f24e68b0, op: WAIT_BITSET|PRIV|CLKRT, utime: 0x7f46f23fedf0, val3: MATCH_ANY) = -1 ETIMEDOUT Connection timed out
