2016-06-08qemu-img bench: Implement -S (step size)Kevin Wolf
With this new option, qemu-img bench can be told to advance the current offset after each request by a different value than the buffer size. This is useful for controlling the conditions for cluster allocation in image formats (e.g. qcow2 cluster allocation with COW in front of the request, or COW areas that aren't overwritten immediately).

2016-06-08block: Don't emulate natively supported pwritev flagsKevin Wolf
Drivers that implement .bdrv_co_pwritev() get the flags passed as an argument to said function, but we also unconditionally emulate the flags anyway. We shouldn't do that.

2016-06-08qcow2: avoid extra flushes in qcow2Denis V. Lunev
The problem with excessive flushing was found by a couple of performance tests: - parallel directory tree creation (from 2 processes) - 32 cached writes + fsync at the end in a loop For the first one results improved from 2.6 loops/sec to 3.5 loops/sec. Each loop creates 10^3 directories with 10 files in each. For the second one results improved from ~600 fsync/sec to ~1100 fsync/sec. Though, it was run on SSD so it probably won't show such performance gain on rotational media. qcow2_cache_flush() calls bdrv_flush() unconditionally after writing cache entries of a particular cache. This can lead to as many as 2 additional fdatasyncs inside bdrv_flush. We can simply skip all fdatasync calls inside qcow2_co_flush_to_os as bdrv_flush for sure will do the job. These flushes are necessary to keep the right order of writes to the different caches. Though this is not necessary in the current code base as this ordering is ensured through the flush in qcow2_cache_flush_dependency(). Signed-off-by: Denis V.

2016-06-08migration/block: Convert load to BlockBackendKevin Wolf
This converts the loading part of block migration to use BlockBackend interfaces rather than accessing the BlockDriverState directly. Note that this takes a lazy shortcut. We should really use a separate BlockBackend that is configured for the migration rather than for the guest (e.g. writethrough caching is unnecessary) and holds its own reference to the BlockDriverState, but the impact isn't that big and we didn't have a separate migration reference before either, so it must be good enough, I guess...

2016-06-08iscsi: Convert to bdrv_co_pwrite_zeroes()Eric Blake
Another step on our continuing quest to switch to byte-based interfaces. As this is the first byte-based iscsi interface, convert is_request_lun_aligned() into two versions, one for sectors and one for bytes. Also, change from outright -EINVAL failure on an unaligned request, to instead failing with -ENOTSUP to trigger a read-modify-write fallback, particularly since the block layer should be honoring bs->request_alignment to avoid -EINVAL on read/write requests.

2016-06-08block: Track write zero limits in bytesEric Blake
Another step towards removing sector-based interfaces: convert the maximum write and minimum alignment values from sectors to bytes. Rename the variables to let the compiler check that all users are converted to the new semantics. The maximum remains an int as long as BDRV_REQUEST_MAX_SECTORS is constrained by INT_MAX (this means that we can't even support a 2G write_zeroes, but just under it) - changing operation lengths to unsigned or to 64-bits is a much bigger audit, and debatable if we even want to do it (since at the core, a 32-bit platform will still have ssize_t as its underlying limit on write()). Meanwhile, alignment is changed to 'uint32_t', since it makes no sense to have an alignment larger than the maximum write, and less painful to use an unsigned type with well-defined behavior in bit operations than to have to worry about what happens if a driver mistakenly supplies a negative alignment. Add an assert that no one was trying to use sectors to get a write zeroes larger than 2G, and therefore that a later conversion to bytes won't be impacted by keeping the limit at 32 bits.

2016-06-08iscsi: Use block size as minimum zero/discard alignmentEric Blake

2016-06-08qcow2: Catch more unaligned write_zero into zero clusterEric Blake
is_zero_cluster() and is_zero_cluster_top_locked() are used only by qcow2_co_write_zeroes(). The former is too broad (we don't care if the sectors we are about to overwrite are non-zero, only that all other sectors in the cluster are zero), so it needs to be called up to twice but with smaller limits - rename it along with adding the neeeded parameter. The latter can be inlined for more compact code. The testsuite change shows that we now have a sparser top file when an unaligned write_zeroes overwrites the only portion of the backing file with data. Based on a patch proposal by Denis V. Lunev.

Unaligned requests will occupy only one cluster. This is true since the previous commit. Simplify the code taking this consideration into account. In other words, the caller is now buggy if it ever passes us an unaligned request that crosses cluster boundaries (the only requests that can cross boundaries will be aligned).

2016-06-08block: split write_zeroes alwaysDenis V. Lunev
We should split requests even if they are less than write_zeroes_alignment. For example we can have the following request: offset 62k size 4k write_zeroes_alignment 64k The original code sent 1 request covering 2 qcow2 clusters, and resulted in both clusters being allocated. But by splitting the request, we can cater to the case where one of the two clusters can be zeroed as a whole, for only 1 cluster allocated after the operation. Signed-off-by: Denis V.
