Hi all: I asked already but there was no answer, so here I go again. I need that a function within a LKM waits for the result of an external processing, I mean, a user land process, id instructed by the LKM to do something, & I need that while this is happening, the LKM waits for the result of that operation. Any hint? thanks in advance israel -- Kernelnewbies: Help each other learn about the Linux kernel.
