https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204298 --- Comment #4 from Scott Long <scottl@FreeBSD.org> --- The bus/topology locks for device reference counting exist only because RCU wasn't available when I did the locking work. I'd really prefer that they went away soon. Would someone be willing to investigate ck_epoch from ConcurrencyKit? We're going to import this library into FreeBSD soon, and ck_epoch provides lockless object lifecycle semantics. -- You are receiving this mail because: You are the assignee for the bug.
