All warnings (new ones prefixed by >>, old ones prefixed by <<):

>> WARNING: modpost: vmlinux.o(.text+0xc28c04): Section mismatch in reference from the function sock_from_file() to the variable .init.text:.LFB3599
The function sock_from_file() references
the variable __init .LFB3599.
This is often because sock_from_file lacks a __init
annotation or the annotation of .LFB3599 is wrong.
