[alsa-devel] memory leak in mmap ops

Hi all,

I found there is a memory leak about 128K every time in linux-2.6.34, but it doesn't exist in linux-3.0. If I use mmap ops in driver the bug will come out, while use copy ops no memory leak. This driver is based on asoc. I tested with aplay to play a wav file. Because there is a lot of changes in ALSA between 2.6.34 and 3.0, so can anyone who familiar with the change history tell me which patch has solved this bug? Thanks in advance.

Scott
