Subject: Anonymous mappings too anonymous.
Date: Fri, 4 Nov 2011 13:54:40 +0200 [thread overview]
Message-ID: <op.v4e7dexl6ywr33@esapekka-pc.rad1> (raw)
Hello!
I have projects which have hundreds of anonymous memory mappings.
I would like to label these mappings similarly like the [heap],
[stack] etc. mappings are labeled in /proc/<pid>/maps.
Code like
mmap(NULL,off,PROT_READ|PROT_WRITE,MAP_PRIVATE|MAP_ANONYMOUS,fd,0);
doesn't work, even if fd is a valid file descriptor.
Ideally I would like to see lines such as
7f0e316e5000-7f0e31ee5000 rw-p 00000000 00:00 0 [my data here]
Is this possible with some sysctl?
t: Esa-Pekka
