Merge tag 'md-3.5' of git://neil.brown.name/md
Pull md updates from NeilBrown: "It's been a busy cycle for md - lots of fun stuff here.. if you like this kind of thing :-) Main features: - RAID10 arrays can be reshaped - adding and removing devices and changing chunks (not 'far' array though) - allow RAID5 arrays to be reshaped with a backup file (not tested yet, but the priciple works fine for RAID10). - arrays can be reshaped while a bitmap is present - you no longer need to remove it first - SSSE3 support for RAID6 syndrome calculations and of course a number of minor fixes etc." * tag 'md-3.5' of git://neil.brown.name/md: (56 commits) md/bitmap: record the space available for the bitmap in the superblock. md/raid10: Remove extras after reshape to smaller number of devices. md/raid5: improve removal of extra devices after reshape. md: check the return of mddev_find() MD RAID1: Further conditionalize 'fullsync' DM RAID: Use md_error() in place of simply setting Faulty bit DM RAID: Record and handle missing devices DM RAID: Set recovery flags on resume md/raid5: Allow reshape while a bitmap is present. md/raid10: resize bitmap when required during reshape. md: allow array to be resized while bitmap is present. md/bitmap: make sure reshape request are reflected in superblock. md/bitmap: add bitmap_resize function to allow bitmap resizing. md/bitmap: use DIV_ROUND_UP instead of open-code md/bitmap: create a 'struct bitmap_counts' substructure of 'struct bitmap' md/bitmap: make bitmap bitops atomic. md/bitmap: make _page_attr bitops atomic. md/bitmap: merge bitmap_file_unmap and bitmap_file_put. md/bitmap: remove async freeing of bitmap file. md/bitmap: convert some spin_lock_irqsave to spin_lock_irq ...
