Analyze and fix the following issue in the Linux kernel code: [SCSI] fix memory leak in initialization
Problem Details: The root cause of the problem is the fact that dev_set_name() now allocates storage instead of using the original array within the kobj. That means that the SCSI assumption that if you haven't made the containing object or any sub objects visible, you can just destroy it (and its component devices) loc...

This fixes up the case when a page mapping disappears between the flush_dcache_page() call (when PG_dcache_dirty is set for the page) and the update_mmu_cache() call -- such as...

Analyze and fix the following issue in the Linux kernel code: USB: xhci: Handle canceled URBs when HC dies.
Problem Details: When the host controller dies (e.g. it is removed from a PCI card slot), the xHCI driver cannot expect commands to complete. The buggy code this patch fixes would mark an URB as canceled and then expect the URB to be completed when the stop endpoint command completed. That would never happen if the h...
