Doesn't work so well for me:
gcc -Wall -W -O2 -g -I. -I.. -I../btt -D_GNU_SOURCE -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 -UCOUNT_IOS -UDEBUG -DNDEBUG -c -o btreplay.o
btreplay.c
btreplay.c: In function ‘pin_to_cpu’:
btreplay.c:554:2: error: request for member ‘__bits’ in something not a
structure or union
CPU_SET_S(tip->cpu, size, &cpus);
This should do it:
- CPU_ZERO_S(ncpus, &cpus);
- CPU_SET_S(tip->cpu, size, &cpus);
+ CPU_ZERO_S(ncpus, cpus);
+ CPU_SET_S(tip->cpu, size, cpus);
