Hi, a question: I need that a function in a LKM waits for a result of an operation performed by a daemon, is like this: - the daemon open a /proc file (I know it should be a /dev file I'll chanche it) - read from it, and if a buffer is empty it go to sleep - then when a sys_open call is made (My_sys_open is called first) it wake up the daemon ho read the path of the file from the buffer, check for certain patterns and return the results to the LKM writing in the /proc (/dev) file Now, what is my question: how can I meke that My_sys_open wait for the result comming via the write function?. Otherwise if someone have another idea.. thanks in advance Israel -- Kernelnewbies: Help each other learn about the Linux kernel.
