Subject: [PATCH] perf build-id: Fix filename size calculation
Date: Tue, 1 May 2012 23:19:36 +0900 [thread overview]
Message-ID: <1335881976-3282-1-git-send-email-namhyung@gmail.com> (raw)
The filename is a pointer variable so the sizeof(filename) will return
length of a pointer. Fix it by using 'size'.
