Sorry, right, that was bad wording. I meant that the lock is not always leaked in this error path - the map lookup needs to succeed initially, after which we need to block for the vnode lock, restart the fault handler, and then get an error from vm_map_lookup(). If the initial lookup fails, there's no leak. _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
