commit 7d573b8d318836ef75d1f2888a50da230b7d83cc
Author: David Smith <dsmith@redhat.com>
Date: Fri Mar 13 16:48:58 2009 -0500
Working bulkmode support.
2009-03-13 David Smith <dsmith@redhat.com>
* print_new.c (stp_print_flush): Added bulkmode support for new
transport.
* transport/ring_buffer.c (__stp_find_next_entry): Fixed syntax
error in bulkmode code.
(_stp_transport_data_fs_init): Changed 'for_each_possible_cpu()'
to 'for_each_online_cpu()' so that non-online cpu's won't have a
trace file created.

More bulkmode support. Only allows for one reader of all trace files.

_stp_trace_reader_cpumask.
(__stp_alloc_ring_buffer): Allocates and clears
_stp_trace_reader_cpumask.
(_stp_data_open_trace): Instead of using an atomic variable, uses
a cpumask variable to allow for only one reader of trace files.
(_stp_data_release_trace): Clears cpumask when trace files are
closed.
