| awreece | I'm noticing a behavior I'm having difficulty explaing -- my application is doing exceptional amounts of `mmap`s from many threads and is contending in the kernel on `mm->mmap_sem`. My expectation is that CPU profiling would reveal this contention; however, I appear to be missing it. | 19:59 |
| awreece | If I use the sched:sched_switch tracepoints with perf, I can very easily see that I'm getting dequeued | 19:59 |
| awreece | I'm surprised that I don't see more CPU usage here: I guess `rwsem_down_read/write_failed` immediately deschedule if it fails? | 20:02 |
| awreece | I must be blind, I don't see anything in the tree documenting rwsem | 20:05 |
| awreece | `git grep rwsem -- Documentation` | 20:05 |
| Noskcaj | Is there any recent change that would cause 15.10 to fail to upgrade to 16.04 with linux-image-4.3.0-2-generic install failure? I think it's lp:1527854 | 21:44 |
