Subject: [BUG] perf: perf trace does not work anymore

Hi,

I am trying to use perf trace to dump the raw samples.

$ perf record -R noploop 5
noploop for 5 seconds
[ perf record: Woken up 3 times to write data ]
[ perf record: Captured and wrote 0.269 MB perf.data (~11759 samples) ]

$ perf trace
  Fatal: reading input file (size expected=3 received=-1)

Seems like trace does not understand the format of the perf.data file anymore.
This used to work. Did you change the purpose of perf trace?
