The funny point is that buffer_head belongs to the filesystem subsystem. What file systems are you using? Could it be that your code just triggers the memory leak, because data is logged to disk, e.g. to /var/log/kern.log ? I have tried your program on my virtual machine (2.6.28) and could see any leak, but maybe data is leaked very slowly... -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.twilightparadox.com _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
