Subject: linux-next: build warnings after merge of the block tree

Hi Jens,

After merging the block tree, today's linux-next build (powerpc
ppc64_defconfig) produced these warnings:

kernel/trace/blktrace.c: In function 'blk_register_tracepoints':
kernel/trace/blktrace.c:999: warning: passing argument 1 of 'register_trace_block_bio_complete' from incompatible pointer type
include/trace/events/block.h:240: note: expected 'void (*)(void *, struct request_queue *, struct bio *, int)' but argument is of type 'void (*)(void *, struct request_queue *, struct bio *)'
kernel/trace/blktrace.c: In function 'blk_unregister_tracepoints':
kernel/trace/blktrace.c:1038: warning: passing argument 1 of 'unregister_trace_block_bio_complete' from incompatible pointer type
include/trace/events/block.h:240: note: expected 'void (*)(void *, struct request_queue *, struct bio *, int)' but argument is of type 'void (*)(void *, struct request_queue *, struct bio *)'

Probably caused by commit de983a7bfcb7c020901ca6e2314cf55a4207ab5a
("block: trace event block fix unassigned field").
