[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH] vnet-module
patch_vnet_1 Replacing the socketcall with direct calling the needed functions (my patch from 28.3) patch_vnet_2 Modify the module-parameter for kernel 2.6.* (the old one will not compile with the actual kernel 2.6.16) Exporting the default-values of the parameters in /sys/module patch_vnet_3 Some "extentions" to error-messages to identify the position in the code. I had searched a bug, but it was a wrong vnet-id ;-/ A hint for docu: using "123459" as vnet-id has not 4 digits and will be punished with errors ;-) -- wbr Robert Valentan diff -r 2604abf98ede tools/vnet/vnet-module/varp_socket.c
