Hi, This would be a silly e-mail but I've not found too much material about that. I was studing at struct turnstile code (kern/subr_turnstile.c, sys/turnstile.h) and there's something is not too clear for me. In particular why owner priority propagation is required in struct turnstile objects? What it does cause? Another question is about sleep mutex implementation; In the comments inside the code I've seen "turnstiles are used to implement not sleepable lock". So why sleep locks are sleeped through turnstiles? They might not use condition variables/sleepqueues?
