perf top: Properly notify the user that vmlinux is missing
Before this patch this message would very briefly appear on the
screen and then the screen would get updates only on the top,
for number of interrupts received, etc, but no annotation would
be performed:
[root@doppio linux-2.6-tip]# perf top -s n_tty_write > /tmp/bla
objdump: '[kernel.kallsyms]': No such file
Now this is what the user gets:
[root@doppio linux-2.6-tip]# perf top -s n_tty_write
Can't annotate n_tty_write: No vmlinux file was found in the
path: [0] vmlinux
[1] /boot/vmlinux
[2] /boot/vmlinux-2.6.33-rc5
[3] /lib/modules/2.6.33-rc5/build/vmlinux
[4] /usr/lib/debug/lib/modules/2.6.33-rc5/vmlinux
[root@doppio linux-2.6-tip]#
This bug was introduced when we added automatic search for
vmlinux, before that time the user had to specify a vmlinux
file.
