md: switch md-cluster to use md_submodle_head

2025-03-04T16:28:39+00:00

To make code cleaner, and prepare to add kconfig for bitmap.

Also remove the unsed global variables pers_lock, md_cluster_ops and
md_cluster_mod, and exported symbols register_md_cluster_operations(),
unregister_md_cluster_operations() and md_cluster_ops.

md/md-cluster: cleanup md_cluster_ops reference

2025-03-04T16:27:47+00:00

md_cluster_ops->slot_number() is implemented inside md-cluster.c, just
call it directly.

md/md-bitmap: make in memory structure internal

2024-08-27T19:43:16+00:00

Now that struct bitmap_page and bitmap is not used externally anymore,
move them from md-bitmap.h to md-bitmap.c (expect that dm-raid is still
using define marco 'COUNTER_MAX').

Also fix some checkpatch warnings.

md/md-bitmap: merge md_bitmap_free() into bitmap_operations

2024-08-27T19:43:15+00:00

So that the implementation won't be exposed, and it'll be possible
o invent a new bitmap by replacing bitmap_operations.

md/md-bitmap: pass in mddev directly for md_bitmap_resize()

2024-08-27T19:43:15+00:00

And move the condition "if (mddev->bitmap)" into md_bitmap_resize() as
well, on the one hand make code cleaner, on the other hand try not to
access bitmap directly.

Since we are here, also change the parameter 'init' from int to bool.
