Couple more bikesheddy things: Is there ever a reason to use a non __builtin_const_p(perms)? Maybe that should be a BUILD_BUG_ON too BUILD_BUG_ON(!builtin_const_p_perms) My brain of little size gets confused by the BUILD_BUG_ON_ZERO(foo) + vs BUILD_BUG_ON(foo); as it just seems like more text for the same content. Is there any value on the "_ZERO(foo) +" I don't understand?

Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. [PATCH 1/8 v4] PCI: define PCI resource names in a 'enum' [PATCH 2/8 v4] PCI: export __pci_read_base

Useful for locating buggy drivers on kernel oops. It may add dozens of new lines to boot dmesg. DEBUG_KOBJECT_RELEASE is hopefully only enabled in debug kernels (like maybe the Fedora rawhide one, or at developers), so being a bit more verbose is likely ok.

Hi Greg, The following two patches move /sys/o2cb into /sys/fs/o2cb as we previously discussed. A symlink is created to maintain compatibility with existing versions of ocfs2-tools. A patch to automatically search /sys/fs/o2cb has been committed to the ocfs2-tools repo and a release with that code shouldn't be too far out. Old versions of ocfs2-tools have been tested and work fine with the
