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.
