Hi all: I have got a problem while I want to open a mutex device, which has been opened by another process. such as /dev/apls9802als, which is opened while the system boot up. But I have to do some test to its read function in its driver provided to the user space. Is there a way that I can close the handler that has been opened and reopen it by the test program I write? Any hacking way for this? Thanks.
