      Freezer: make kernel threads nonfreezable by default · 83144186
      Rafael J. Wysocki authored
      Currently, the freezer treats all tasks as freezable, except for the kernel
      threads that explicitly set the PF_NOFREEZE flag for themselves.  This
      approach is problematic, since it requires every kernel thread to either
      set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't
      care for the freezing of tasks at all.
      
      It seems better to only require the kernel threads that want to or need to
      be frozen to use some freezer-related code and to remove any
      freezer-related code from the other (nonfreezable) kernel threads, which is
      done in this patch.
      
      The patch causes all kernel threads to be nonfreezable by default (ie.  to
      have PF_NOFREEZE set by default) and introduces the set_freezable()
      function that should be called by the freezable kernel threads in order to
      unset PF_NOFREEZE.  It also makes all of the currently freezable kernel
      threads call set_freezable(), so it shouldn't cause any (intentional)
      change of behaviour to appear.  Additionally, it updates documentation to
      describe the freezing of tasks more accurately.

      USB: add USB-Persist facility · 0458d5b4
      Alan Stern authored
      This patch (as886) adds the controversial USB-persist facility,
      allowing USB devices to persist across a power loss during system
      suspend.
      
      The facility is controlled by a new Kconfig option (with appropriate
      warnings about the potential dangers); when the option is off the
      behavior will remain the same as it is now.  But when the option is
      on, people will be able to use suspend-to-disk and keep their USB
      filesystems intact -- something particularly valuable for small
      machines where the root filesystem is on a USB device!

      [PATCH] Cleanup patch for process freezing · 3e1d1d28
      Christoph Lameter authored
      1. Establish a simple API for process freezing defined in linux/include/sched.h:
      
         frozen(process)		Check for frozen process
         freezing(process)		Check if a process is being frozen
         freeze(process)		Tell a process to freeze (go to refrigerator)
         thaw_process(process)	Restart process
         frozen_process(process)	Process is frozen now
      
      2. Remove all references to PF_FREEZE and PF_FROZEN from all
         kernel sources except sched.h
      
      3. Fix numerous locations where try_to_freeze is manually done by a driver
      
      4. Remove the argument that is no longer necessary from two function calls.
      
      5. Some whitespace cleanup
      
      6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
         cleared before setting PF_FROZEN, recalc_sigpending does not check
         PF_FROZEN).
      
      This patch does not address the problem of freeze_processes() violating the rule
      that a task may only modify its own flags by setting PF_FREEZE. This is not clean
      in an SMP environment. freeze(process) is therefore not SMP safe!

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
