Last sentence was supposed to mean: Before the char device is being registered, a driver's module_init has to have set up everything that's going to be used by openers of the file. (Traditionally, the BKL serialized open() with module initialization, which was not obvious to driver writers because it happened deep in the core kernel.) -- Stefan Richter -=====-==-=- -=-- ----= http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
