302a3c0f2757ae1a3e7df3f9fa1f20e2214ab945 is the first bad commit commit 302a3c0f2757ae1a3e7df3f9fa1f20e2214ab945 Author: K. Y. Srinivasan Date: Sun Feb 17 11:30:44 2013 -0800 Drivers: hv: vmbus: Use the new infrastructure for delivering VMBUS interrupts Use the infrastructure for delivering VMBUS interrupts using a special vector. With this patch, we can now properly handle the VMBUS interrupts that can be delivered on any CPU. Also, turn on interrupt load balancing as well. This patch requires the infrastructure that was implemented in the patch: X86: Handle Hyper-V vmbus interrupts as special hypervisor interrupts Signed-off-by: K. Y.

superblocks as they are read from disk Add a superblock verify callback function and pass it into the buffer read functions. Remove the now redundant verification code that is currently in use. Adding verification shows that secondary superblocks never have their "sb_inprogress" flag cleared by mkfs.xfs, so when validating the secondary superblocks during a grow operation we have to avoid checking this field. Even if we fix mkfs, we will still have to ignore this field for verification purposes unless a version of mkfs that does not have this bug was used.
