I'm getting the following new (compared to k 4.2 on Debian Wheezy) compiler warnings when I build k 4.3 on Debian Jessie. It would be nice to get rid of them, because otherwise it gets hard to find real issues appearing during build. Same applies to 'old' tls module warnings. -- Juha ------------------------------------------------------------------------------------------------------------------------------ CC (gcc) [sip-proxy] mem/tlsf.o mem/tlsf.c:583:24: warning: 'block_trim_free_leading' defined but not used [-Wunused-function] static block_header_t* block_trim_free_leading(control_t* control, block_header_t* block, size_t size) ^ ...
