Andy Isaacson 0f2c3de2ba perf session: fix error message on failure to open perf.data ... If we cannot open our data file, print strerror(errno) for a more comprehensible error message; and only suggest 'perf record' on ENOENT. In particular, this fixes the nonsensical advice when: % sudo perf record sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.009 MB perf.data (~381 samples) ] % perf trace failed to open file: perf.data (try 'perf record' first) % Cc: Ingo Molnar <mingo@elte.hu> LPU-Reference: <20100612033615.GA24731@hexapodia.org> Signed-off-by: Andy Isaacson <adi@hexapodia.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>		2010-06-17 13:55:54 -03:00
