As rw_enter() returns a errno on failure mutex_lock_interruptible() negated the return value. But this did not account for ERESTART being -1 which would return 1 to the caller. sthen@ periodically hit a uvm_fault() in i915_request_create() which was caused by attempting to use 1 as a pointer. ok kettenis@ reduce the diff to linux 2020-06-19T09:17:51Z jsg jsg@openbsd.org 2020-06-19T09:17:51Z urn:sha1:1cf3647954f45deaa7c593886578039581249d21 use atomic_set() in kref_init() 2020-06-17T02:58:15Z jsg jsg@openbsd.org 2020-06-17T02:58:15Z urn:sha1:614b21422bdaf08388131ae1ec08e4f75d140411 kref_sub() interface was removed from linux and is unused 2020-06-17T02:06:05Z jsg jsg@openbsd.org 2020-06-17T02:06:05Z urn:sha1:3519e381ef5fc28d9679f4a7bb159fa22baf6c33 use WRITE_ONCE and READ_ONCE for set and read 2020-06-17T01:03:57Z jsg jsg@openbsd.org 2020-06-17T01:03:57Z urn:sha1:b40fc73fbdba799cae45a0550f11b49fedd1b21b ok kettenis@ remove some unused defines 2020-06-16T15:10:03Z jsg jsg@openbsd.org 2020-06-16T15:10:03Z urn:sha1:24a9071d1bb1560c2918d6136528e2f176b6009a implement atomic_inc_not_zero() by way of atomic_add_unless() 2020-06-16T14:35:12Z jsg jsg@openbsd.org 2020-06-16T14:35:12Z urn:sha1:5cf16f9f28d6fe6b5339014fb438916efb9d5df7
