This introduces a lock-order relationship with the softdep lock that can not otherwise be resolved. - Don't set B_DONE until bufdone() is complete, otherwise another processor may believe the buf is done before it is. - Only acquire Giant if the caller has set b_iodone. Don't grab giant around normal bufdone() calls. Sponsored By: Isilon Systems, Inc. |
