Rafael Kitover e0cd6c28a3 kernel timer API rework ... In `config/kernel-timer.m4` refactor slightly to check more generally for the new `timer_setup()` APIs, but also check the callback signature because some kernels (notably 4.14) have the new `timer_setup()` API but use the old callback signature. Also add a check for a `flags` member in `struct timer_list`, which was added in 4.1-rc8. Add compatibility shims to `include/spl/sys/timer.h` to allow using the new timer APIs with the only two caveats being that the callback argument type must be declared as `spl_timer_list_t` and an explicit assignment is required to get the timer variable for the `timer_of()` macro. So the callback would look like this: ```c __cv_wakeup(spl_timer_list_t t) { struct timer_list *tmr = (struct timer_list *)t; struct thing *parent = from_timer(parent, tmr, parent_timer_field); ... /* do stuff with parent */ ``` Make some minor changes to `spl-condvar.c` and `spl-taskq.c` to use the new timer APIs instead of conditional code.
