Not my day it seems ! Hopefully I remembered to attach the file this time :) -- Hi, this patch adds Solaris 7/8 like /dev/poll support to the kernel. I can claim no real credit for this as basically this is a fixed version of a patch available from http://www.citi.umich.edu/projects/linux-scalability/ to compile correctly with 2.4.5 that only seemed to work with the 2.3.x devel branch. The reason for this is so I can compile & test an application on my home linux pc when I'm not around my nice work Solaris boxes :) Please note, I have not got the knowledge of kernel development to know if this patch is broken or badly written. It may be bugged and/or worse than the standard poll() call but my application works so I'll leave profiling etc to people more knowledgable than me. Vince.
