The sys_inotify* calls are defined if the target supports them and the

tcg/x86_64: optimize register allocation order
The beginning of the register allocation order list on the TCG x86_64
target matches the list of clobbered registers. This means that when an
helper is called, there is almost always clobbered registers that have
to be spilled.
The same way register %rsi and %rdi are at the top of the register
allocation order list, while they can't be used for load/store
operations. This means the data and/or address registers are very often
%rsi and %rdi, and their values have to be spilled, and then moved back
to another register.
This patches changes to the allocation order to avoid those effects.
It results in a 8% gain speed in qemu-x86_64 to compress a bzip2 file,
and a 6% gain in qemu-system-mips64 to compile a small application.

This patch adds a new qemu-io tool that links against the block layer and

It is inspired by the xfs_io tool which does the same for plain file I/O.
In fact the libxcmd library which is the backend of xfs_io is reused by this
tool in a limited fashing (cmd.[ch] files).
This version tests out most of the plain block I/O commands with the
most notable absent commands beeing snapshot handling and real aio.

Add host_device support to qemu-img. (Nolan Leake)
This patch allows the use a host_device as the destination for "qemu-img
convert".
I added a ->bdrv_create function host_device. It merely verifies that
the device exists and is large enough.
A check is needed in the qemu-img convert loop to ensure that we write
out all 0 sectors to the host_device. Otherwise they end up with stale
garbage where all zero sectors were expected.
I also made the check against bdrv_is_allocated enabled for everything
_except_ host devices, since there is no point in making the block
backend write a bunch of zeros just so that we can memcmp them
immediately afterwards. Host devices can't benefit from this because
there is no way to differentiate between a sector being unallocated
because it was never written, or because it was written with all zeros
and then made a trip through qemu-img convert.
Finally, there is an unrelated fix for a typo in the error message
printed if the destination device does not support ->bdrv_create.

Fix (at least one cause of) qcow2 corruption. (Nolan Leake)
qcow2's get_cluster_offset() scans forward in the l2 table to find other
clusters that have the same allocation status as the first cluster.
This is used by (among others) qcow_is_allocated().
Unfortunately, it was not checking to be sure that it didn't fall off
the end of the l2 table. This patch adds that check.
The symptom that motivated me to look into this was that
bdrv_is_allocated() was returning false when there was in fact data
there. This is one of many ways this bug could lead to data corruption.
I checked the other place that scans for consecutive unallocated blocks
(alloc_cluster_offset()) and it appears to be OK:
nb_clusters = MIN(nb_clusters, s->l2_size - l2_index);
appears to prevent the same problem from occurring.

fix format string warnings in block-qcow2.c (Christoph Hellwig)
Recent patches added two compiler warnings about the format string
usage in qcow_read_extensions. One is printing a uint64_t using
%lu which is incorrect on many platforms as it can be a unsigned
long long, the second one is printing the result of sizeof as
%lu, but it is a size_t so it needs to be printed using %zu.

check for bs->drv in bdrv_flush (Christoph Hellwig)
All the bdrv_ helpers should check for bs->drv being zero as that means
there is no backend image open. bdrv_flush fails to perform that check
and can thus cause NULL pointer dereferences.
Found using qemu-io.

remove dead code in bdrv_check_request (Christoph Hellwig)
Remove code dealing with negative sector numbers for byte access in
bdrv_check_request as sector numbers can't ever be negative.
Previously we supported negative sector counts for byte access, but
