The BLKFLSBUF ioctl doesn't send the flush bio to the block device, thus
flushed data may be lurking in the disk cache and they may not be really
flushed to the stable storage.
This patch adds the call to blkdev_issue_flush to blkdev_flushbuf.

In the past, the function __vmalloc didn't respect the GFP flags - it
allocated memory with the provided gfp flags, but it allocated page tables
with GFP_KERNEL. This was fixed in the commit
451769ebb7e792c3404db53b3c2a422990de654e, so the memalloc_noio_save /
memalloc_noio_restore workaround is
If memory allocation fails, try to reduce the size of the recalculate
buffer and continue with the smaller buffer.

dm-integrity preallocated 8MiB buffer for recalculating in the constructor
and freed it in the destructor. This wastes memory when the user has many
dm-integrity devices.
This patch changes dm-integrity so that it allocates the buffer in the
begining of the function integrity_recalc and free it
It was reported that dm-integrity runs out of vmalloc space on 32-bit
architectures. On x86, there is only 128MiB vmalloc space and dm-integrity
consumes it quickly because it has 64MiB journal and 8MiB recalculate
buffer.
This patch reduces the size of the journal to 4MiB and the size of the

Recently, I found that the used space of the thin-pool will keep rising if I
use dm-thin as follow:

Hi, Mike,
Sorry for the noise. This patch has been proposed for a long time. I
wonder does there any suggestion for the patch. Looking forward to your
reply!
Thanks,
