md-cluster/bitmap: unplug bitmap to sync dirty pages to disk
This patch is doing two distinct but related things.
1. It adds bitmap_unplug() for the main bitmap (mddev->bitmap). As bit
have been set, BITMAP_PAGE_DIRTY is set so bitmap_deamon_work() will
not write those pages out in its regular scans, only bitmap_unplug()
will. If there are no writes to the array, bitmap_unplug() won't be
called, so we need to call it explicitly here.
2. bitmap_write_all() is a bit of a confusing interface as it doesn't
actually write anything. The current code for writing "bitmap" works
but this change makes it a bit clearer.
