sysmips call and glibc atomic set

2000-12-24 Thread Joe deBlaquiere
} QUESTION 3) I notice that the code for this particular case of sysmips has changed recently. The old code looked more like the 'll/sc' version of glibc above. I would think that the 'll/sc' code would be better on SMP systems. Is there a good reason why this revert

I'm trying to test a communications path to a remote system and was wondering if I could force the DF bit on some UDP traffic. Does anybody know of a way to do this?? TIA, Joe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED

A few things come to mind: 1. Is your init statically linked or linked with shared libraries? If it's shared, do you have all the shared objects on your disk image in a place where they can be found (/lib, I hope)? You might try linking it statically (but stripped) just to make sure. 2. Is it
