[ltt-dev] [PATCH 2/2] Fix lttd's compile warning on fc9

[Zhaolei]

Hi,

Fixed following compile warning:

gcc -DHAVE_CONFIG_H -I.. -I..     -g -O2 -MT lttd.o -MD -MP -MF .deps/lttd.Tpo -c -o lttd.o lttd.c
lttd.c: In function 'read_subbuffer':
lttd.c:467: warning: passing argument 2 of 'splice' from incompatible pointer type

It can be fixed by following patch. Applies on top of ltt-control-0.58-23112008.
