Hi Neil,

After merging the md tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from drivers/md/raid1.c:40:0:
drivers/md/raid1.h:71:2: error: expected ':', ',', ';', '}' or '__attribute__' before 'int'

and went downhill from there ...

Caused by commit 9d64362373aa ("md/raid1:  add documentation to
r1_private_data_s data structure").  Please build test ...

I have used the md tree from next-20111006 for today.

Hi all,

With the merge window opening, just a reminder that this merge fixup is
still required.

One simple question, isn't the sector_div used for change '%' operator?
but the modified line is:

bm_blocks = bitmap->mddev->resync_max_sectors */* (bitmap->mddev->bitmap_info.chunksize >> 9);

But, the modified is:

bm_blocks = sector_div(bitmap->mddev->resync_max_sectors,
		       bitmap->mddev->bitmap_info.chunksize >> 9);

The sector_div returns:

bitmap->mddev->resync_max_sectors % bitmap->mddev->bitmap_info.chunksize >> 9

So it basically means :

bm_blocks = bitmap->mddev->resync_max_sectors % bitmap->mddev->bitmap_info.chunksize >> 9


And maybe the current next tree should add the following change to keep
original semantic.

Thanks!
sector_div() leave the remainder in it's first argument, so this isn't quite
correct - you need to store resync_max_sectors in a temp variable.
So I made that change and applied you patch.

Thanks,

I tried that and it was not sufficient.

The second also changes this:

bm_blocks = sector_div(bitmap->mddev->resync_max_sectors, (chunksize >> 9));

(added by the first) to this:

bm_blocks = bitmap->mddev->resync_max_sectors / (bitmap->mddev->bitmap_info.chunksize >> 9);

where bitmap->mddev->resync_max_sectors is a sector_t ...

Thanks.
I think
+               bm_blocks = DIV_ROUND_UP(bm_blocks, 4096);

needs DIV_ROUND_UP_SECTOR_T()


The first patch you identified adds that line.  The second relocates it.

I've queued a fix-up for now, but I might get it merged back into the
original...


Thanks,

Hi Neil,

After merging the md tree, today's linux-next build (i386 defconfig)
failed like this:

drivers/built-in.o: In function `bitmap_read_sb':
bitmap.c:(.text+0x29cd52): undefined reference to `__udivdi3'

Probably caused by commit b97e92574c0b ("Use separate bitmaps for each
nodes in the cluster") or commit f9209a323547 ("bitmap_create returns
bitmap pointer").

I reverted the md tree for today (because I am not sure how to fix
this and reverting less became messy).

Or just ask Jens if you can submit that patch through your tree (with his

Hi Neil,

After merging the md tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: "__tracepoint_block_unplug" [drivers/md/raid456.ko] undefined!

Presumably caused by commit 14817e9a6dab ("md/raid5: add blktrace calls").

CONFIG_MD_RAID456=m

I have used the md tree from next-20120924 for today.

Thanks a lot Stephen.

I've add the missing EXPORT_SYMBOL_GPL(), so should be fine for next time
round.

While on the subject it would be nice to factor this out into a

Sorry 'bout that.  I noticed not long after I had pushed out for-next and
fixed it.  You must have pulled during that window :-(

I'll add dm-raid back in to my build testing - I don't know why it dropped
out.

This will be fixed for tomorrow.
I might add the merge with the block layer too.

Thanks,

Hi Neil,

After merging the md tree, today's linux-next build (x86_64_allmodconfig)
failed like this:

Caused by commits 4251a3bcf0e1 ("md: removing typedefs:  mdk_rdev_t ->
struct md_rdev") and 724d5bc7708a ("md: remove typedefs: mddev_t ->
struct mddev").

Have you dropped better versions of these commits?  Please build test.

I have used the version of the tree from next-20111006 since
next-20111007 had another build problem.
