In order to save space I did not change what we have. Every build starts from a mrproper and new configuration. I can not mix LTO/non-LTO in this case. I'm using upstream defconfig and upstream defconfig + LTO enabled and the result is that spl increase in size for LTO building. I'm working to keep out part that are not really needed but I was hoping that LTO give me some help here Michael > -- > Tom -- Michael Nazzareno Trimarchi Co-Founder & Chief Executive Officer M. +39 347 913 2170 mich...@amarulasolutions.com __________________________________ Amarula Solutions BV Joop Geesinkweg 125, 1114 AB, Amsterdam, NL T. +31 (0)85 111 9172 i...@amarulasolutions.com www.amarulasolutions.com
