Hi,
I'm going through txg_hold_open where 'CPU_SEQID' has been used to get the
index into tx_cpu.
#define max_ncpus 64
#define CPU_SEQID ((uintptr_t)pthread_self() & (max_ncpus - 1))
uint64_t
txg_hold_open(...) {
...
tc = &tx->tx_cpu[CPU_SEQID];
...
}
Not sure whether it is intended behavior (or) not, but, this 'CPU_SEQID'
macro always get evaluated as 0 in Linux.
Reason is: lower order 8 bits of value returned from pthread_self()
consists of 0's.
Do you guys see any issue here or is that fine this way?
Thanks,
Vishnu
