Hi,

Some small perf fixes, mostly caught with valgrind.

The last patch is a simplification: it is easier to open /proc/self/exe
than /proc/$pid/exe.

Tommi Rantala (6):
perf buildid: do not update SDT cache with null filename
perf buildid: do not assume that readlink() returns a null terminated
string
perf tests: do not assume that readlink() returns a null terminated
string
perf utils: use sizeof(buf)-1 in readlink() call
perf utils: null terminate buf in read_ftrace_printk()
perf utils: readlink /proc/self/exe to find the perf binary
