Revert "perf record: Intercept all events"
This reverts commitf5a2c3dce0
. This patch is required for making "perf lock rec" work. The commitf5a2c3dce0
changes write_event() of builtin-record.c . And changed write_event() sometimes doesn't stop with perf lock rec. Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> LKML-Reference: <new-submission> [ that commit also causes perf record to not be Ctrl-C-able, and it's concetually wrong to parse the data at record time (unconditionally - even when not needed), as we eventually want to be able to do zero-copy recording, at least for non-archive recordings. ] Signed-off-by: Ingo Molnar <mingo@elte.hu>
