[PATCH 0/6] perf string handling fixes

[Tommi Rantala]

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
