Do you have a clue? Without this patch, 'emacs kernel/built-in.o' 'cat kernel/built-in.o' 'less kernel/built-in.o' showed me the same content. $ less kernel/built-in.o | head -n 10 !<thin> // 2964 ` fork.o/ exec_domain.o/ panic.o/ cpu.o/ exit.o/ softirq.o/ resource.o/ sysctl.o/ After applying this patch, 'less kernel/built-in.a' is strange. $ less kernel/built-in.a | head -n 10 rw-r--r-- 0/0 60216 Jan 1 09:00 1970 kernel/fork.o rw-r--r-- 0/0 3648 Jan 1 09:00 1970 kernel/exec_domain.o rw-r--r-- 0/0 20552 Jan 1 09:00 1970 kernel/panic.o rw-r--r-- 0/0 87752 Jan 1 09:00 1970 kernel/cpu.o rw-r--r-- 0/0 34136 Jan 1 09:00 1970 kernel/exit.o rw-r--r-- 0/0 41448 Jan 1 09:00 1970 kernel/softirq.o rw-r--r-- 0/0 40904 Jan 1 09:00 1970 kernel/resource.o rw-r--r-- 0/0 60968 Jan 1 09:00 1970 kernel/sysctl.o rw-r--r-- 0/0 4472 Jan 1 09:00 1970 kernel/sysctl_binary.o rw-r--r-- 0/0 12472 Jan 1 09:00 1970 kernel/capability.o However, 'cat kernel/built-in.a' works as I expect. $ cat kernel/built-in.a | head -n 10 !<thin> // 2964 ` fork.o/ exec_domain.o/ panic.o/ cpu.o/ exit.o/ softirq.o/ resource.o/ sysctl.o/ Is my 'less' insane? Or, is this intentional behavior of 'less'? -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
