Subject: VG_(di_notify_mmap): don't complain about being unable to stat64/stat files in /dev... 
X-Git-Tag: VALGRIND_3_14_0~149

VG_(di_notify_mmap): don't complain about being unable to stat64/stat files in /dev/shm/.

Some applications cause this message to be emitted hundreds of times, which is annoying.
