      workqueue: don't perform NUMA-aware allocations on offline nodes in wq_numa_init() · 1be0c25d
      Tejun Heo authored
      wq_numa_init() builds per-node cpumasks which are later used to make
      unbound workqueues NUMA-aware.  The cpumasks are allocated using
      alloc_cpumask_var_node() for all possible nodes.  Unfortunately, on
      machines with off-line nodes, this leads to NUMA-aware allocations on
      existing bug offline nodes, which in turn triggers BUG in the memory
      allocation code.
      
      Fix it by using NUMA_NO_NODE for cpumask allocations for offline
      nodes.

      Pull Ceph fixes from Sage Weil:
       "Yes, this is a much larger pull than I would like after -rc1.  There
        are a few things included:
      
         - a few fixes for leaks and incorrect assertions
         - a few patches fixing behavior when mapped images are resized
         - handling for cloned/layered images that are flattened out from
           underneath the client
      
        The last bit was non-trivial, and there is some code movement and
        associated cleanup mixed in.  This was ready and was meant to go in
        last week but I missed the boat on Friday.  My only excuse is that I
        was waiting for an all clear from the testing and there were many
        other shiny things to distract me.
      
        Strictly speaking, handling the flatten case isn't a regression and
        could wait, so if you like we can try to pull the series apart, but
        Alex and I would much prefer to have it all in as it is a case real

      cpufreq: Preserve sysfs files across suspend/resume · a66b2e50
      Srivatsa S. Bhat authored
      The file permissions of cpufreq per-cpu sysfs files are not preserved
      across suspend/resume because we internally go through the CPU
      Hotplug path which reinitializes the file permissions on CPU online.
      
      But the user is not supposed to know that we are using CPU hotplug
      internally within suspend/resume (IOW, the kernel should not silently
      wreck the user-set file permissions across a suspend cycle).
      Therefore, we need to preserve the file permissions as they are
      across suspend/resume.
      
      The simplest way to achieve that is to just not touch the sysfs files
      at all - ie., just ignore the CPU hotplug notifications in the
      suspend/resume path (_FROZEN) in the cpufreq hotplug callback.

      ACPI / scan: Fix memory leak on acpi_scan_init_hotplug() error path · 7a26b530
      Catalin Marinas authored
      Following commit 6b772e8f (ACPI: Update PNPID match handling for
      notify), the acpi_scan_init_hotplug() calls acpi_set_pnp_ids() which
      allocates acpi_hardware_id and copies a few strings (kstrdup). If the
      devices does not have hardware_id set, the function exits without
      freeing the previously allocated ids (and kmemleak complains). This
      patch calls simply changes 'return' on error to a 'goto out' which
      calls acpi_free_pnp_ids().
