Hi,
An issue on solaris�:
Anonymous mmap must have a fd set to -1 in order to work (on linux, it is ignored), in alloc_mem_mmap, the fd is set to 1
[.]
static int alloc_mem_mmap(struct thread_data *td, size_t total_mem)
{
��������������� int flags = 0;
��������������� td->mmapfd = 1;
��������������� if (td->o.mem_type == MEM_MMAPHUGE) {
[.]
Changing it to -1 makes the code working fine.
Bye
Seb

That actually just looks like a typo, it makes no sense for this to be
'1'... I'll fix it, thanks for finding it!
