One\ndirect clue is that when we call io_add_watch_poll() sometimes we are\nstill passing in the NULL context pointer.\n\nIIUC we are fine during setup since the context will be passed\ncorrectly during setup via chr_update_read_handler(). However it\nwon't survive if chardev reconnected due to some reason.\n\nThis series tries to solve above problem by caching the gcontext\npointer in Chardev itself.\n\nThis will be required for the monitor OOB (out-of-band) support, since\nin that series monitor backends may be run in non-default contexts.\n\nPlease review.
