Hi guys, I've been using blocks for a while and found that current behavior is error prone. So I am going to propose to you the better one. Motivation: 1) The __weak variables in blocks are very common pattern. So having any implicit default behavior makes thing worse. 2) Some stupid mistakes like: __weak typeof (self) theSelf = self; ...^ { theSelf.blabla = .. .... [self blabla]; // ups, calling self directly is an error _ivar = … // or implic...

Hmm... well adding the __export stopped the "undefined symbol" error from showing up when I add "SENDCOOKIES" in the config, however I'm still not seeing any cookies being sent to my webserver. Any ideas on how to further debug? (if you want to send me the debug compile options privately that's okay too) -----Original Message----- From: H. Peter Anvin [mailto:hpa at

Hi all, The series is a draft of generic MSI driver that supports PCI and Non-PCI device which have MSI capability. If you're not interested it, sorry for the noise. The series is based on Linux-3.16-rc1. MSI was introduced in PCI Spec 2.2. Currently, kernel MSI driver codes are bonding with PCI device. Because MSI has a lot advantages in design. More and more non-PCI devices want to use

An architecture protecting the guest memory against unauthorized host access may want to enforce VIRTIO I/O device protection through the use of VIRTIO_F_IOMMU_PLATFORM.
