dm integrity: reduce vmalloc space footprint on 32-bit architectures
[ Upstream commit 6d50eb4725
]
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 a 64MiB journal and 8MiB recalculate
buffer.
Fix this by reducing the size of the journal to 4MiB and the size of
the recalculate buffer to 1MiB, so that multiple dm-integrity devices
can be created and activated on 32-bit architectures.
