Yes, but get_timer() is not guaranteed to return 0 to MAX_ULONG, as far as I can tell. On MIPS (even after my CFG_HZ patch), get_timer() will only return 0 to 14316 on a 300MHZ machine, as the 32-bit MIPS tick timer that forms the MIPS time base wraps to 0 after 14.316 seconds. > I tend to reject this patch because I think we should fix the cause > of the problems rather than the symptoms - there are more areas in > the code that rely on sane behaviour of the get_timer() functione. Well, then we've got a big problem on MIPS. Jason McMullan MTS SW System Firmware NetApp 724.741.5011 Fax 724.741.5166 Direct 412.656.3519 Mobile [EMAIL PROTECTED] www.netapp.com
