      dm raid1: handle log failure · fc1ff958
      Jonathan Brassow authored
      When writing to a mirror, the log must be updated first.  Failure
      to update the log could result in the log not properly reflecting
      the state of the mirror if the machine should crash.
      
      We change the return type of the rh_flush function to give us
      the ability to check if a log write was successful.  If the
      log write was unsuccessful, we fail the writes to avoid the
      case where the log does not properly reflect the state of the
      mirror.
      
      A follow-up patch - which is dependent on the ability to
      requeue I/O's to core device-mapper - will requeue the I/O's
      for retry (allowing the mirror to be reconfigured.)

      dm raid1: handle resync failures · f44db678
      Jonathan Brassow authored
      Device-mapper mirroring currently takes a best effort approach to
      recovery - failures during mirror synchronization are completely ignored.
      This means that regions are marked 'in-sync' and 'clean' and removed
      from the hash list.  Future reads and writes that query the region
      will incorrectly interpret the region as in-sync.
      
      This patch handles failures during the recovery process.  If a failure
      occurs, the region is marked as 'not-in-sync' (aka RH_NOSYNC) and added
      to a new list 'failed_recovered_regions'.
      
      Regions on the 'failed_recovered_regions' list are not marked as 'clean'
      upon removal from the list.  Furthermore, if the DM_RAID1_HANDLE_ERRORS
      flag is set, the region is marked as 'not-in-sync'.  This action prevents
      any future read-balancing from choosing an invalid device because of the
      'not-in-sync' status.
      
      If "handle_errors" is not specified when creating a mirror (leaving the
      DM_RAID1_HANDLE_ERRORS flag unset), failures will be ignored exactly as they
      would be without this patch.  This is to preserve backwards compatibility with
      user-space tools, such as 'pvmove'.  However, since future read-balancing
      policies will rely on the correct sync status of a region, a user must choose
      "handle_errors" when using read-balancing.

      dm: disable barriers · 07a83c47
      Stefan Bader authored
      This patch causes device-mapper to reject any barrier requests.  This is done
      since most of the targets won't handle this correctly anyway.  So until the
      situation improves it is better to reject these requests at the first place.
      Since barrier requests won't get to the targets, the checks there can be
      removed.

      dm raid1: clear region outside spinlock · 943317ef
      Jonathan Brassow authored
      A clear_region function is permitted to block (in practice, rare) but gets
      called in rh_update_states() with a spinlock held.
      
      The bits being marked and cleared by the above functions are used
      to update the on-disk log, but are never read directly.  We can
      perform these operations outside the spinlock since the
      bits are only changed within one thread viz.
         - mark_region in rh_inc()
         - clear_region in rh_update_states().
      
      So, we grab the clean_regions list items via list_splice() within the
      spinlock and defer clear_region() until we iterate over the list for
      deletion - similar to how the recovered_regions list is already handled.
      We then move the flush() call down to ensure it encapsulates the changes
      which are done by the later calls to clear_region().

      Milan Broz authored
      Process persistent exception store metadata IOs in a separate thread.
      
      A snapshot may become invalid while inside generic_make_request().
      A synchronous write is then needed to update the metadata while still
      inside that function.  Since the introduction of
      md-dm-reduce-stack-usage-with-stacked-block-devices.patch this has to
      be performed by a separate thread to avoid deadlock.

      The RTC library code contains everything necessary to set the

      commit, it's far better to let the RTC library code sort this
      out rather than implement something which might not be
      appropriate for everyone.

      [ARM] sa1100: stop doing our own rtc management over suspend · f3ebbc20
      Russell King authored
      Remove the RTC management over a suspend/resume cycle.  As per the
      corresponding PXA patch, the RTC library code handles updating
      system time on resume.

      The last two slots of MAP 00b of ich6m was incorrectly marked as
      reserved.  This is left over from converting the entry to allow 00b.
      This causes no real problem.  It only makes the driver print annoying
      warning message.  Fix it.

      * Set I/O Id field in descriptor, where present.  Appears to work
        fine on all versions, even though queueing is still disabled.
      * call pci_set_mwi(), to (a) make sure cacheline size is set properly,
        and (b) enable MWI transactions
      * Remove never-used handling of coalescing interrupt bits (these events
        are always masked)
