Be sure to invalidate a vdev's cache before performing
a zpool labelclear. There are cases where the cache is
stale because we did some operation that bypassed it,
and since we are doing an open with only O_RDWR, we
should invalidate it to be safe.

musl's sys/errno.h is literally:
/#warning redirecting incorrect #include <sys/errno.h> to <errno.h>
/#include <errno.h>
It does the same for sys/{poll,signal}.h. This is rather noisy when
building ZoL against musl. musl is also correct in pointing out that the
correct headers are outside of sys/ according to the single unix
specification:
http://pubs.opengroup.org/onlinepubs/7908799/xsh/errno.h.htmlhttp://pubs.opengroup.org/onlinepubs/7908799/xsh/poll.h.htmlhttp://pubs.opengroup.org/onlinepubs/7908799/xsh/signal.h.html
Lets implement our own sys/* versions of these headers to redirect to
the proper userland ones when building in userspace. That will silence
the warning.
There are also some instances where we include incorrectly from sys/ or
from outside of sys/ in userspace only code. In these instances, lets
just fix the includes directly.

Porting Notes:
- Updated 'zpool labelclear' and 'zdb -l' such that they attempt
to find a vdev given solely its short name. This behavior is
consistent with the upstream OpenZFS code and the test cases
depend on it. The actual implementation differs slightly due
to device naming conventions on Linux.
- auto_online_001_pos, auto_replace_001_pos and add-o_ashift
test cases updated to expect failure when no label exists.
- read_efi_label() and zpool_label_disk_check() are read-only
operations and should use O_RDONLY at open time to enforce this.
- zpool_label_disk() and zpool_relabel_disk() write the partition
information using O_DIRECT an fsync() and page cache invalidation

- dump_label() in zdb should invalidate the page cache in order

When we try assign a new transaction to a TXG we must know beforehand
if there is sufficient free space on disk. This is to decide,
in dmu_tx_assign(), if we should reject the TX with ENOSPC.
We rely on spa_get_worst_case_asize() to inflate the size of our
logical writes by a factor of spa_asize_inflation which is
calculated as:
(VDEV_RAIDZ_MAXPARITY + 1) * SPA_DVAS_PER_BP * 2 == 24
The problem with the current implementation is that we don't take
into account what happens with very small writes on VDEVs with large
physical block sizes.
Consider the case of writes to a dataset with recordsize=512,
copies=3 on a VDEV with ashift=13 (usually SSD with 8K block size):
every logical IO will end up allocating 3 * 8K = 24K on disk, so 512
bytes multiplied by 48, which is double the size we account for.
If we allow this kind of writes to be assigned a TX it is possible,
when the pool is almost full, to trigger an allocation failure
(ENOSPC) in the ZIO pipeline, which will in turn result in the whole
pool being suspended.
The bug is fixed by using, in spa_get_worst_case_asize(), the MAX()
value chosen between the logical io size from zfs_write() and the
maximum physical block size used among our VDEVs.

RAID-Z requires that space be allocated in multiples of P+1 sectors,
because this is the minimum size block that can have the required amount
of parity. Thus blocks on RAIDZ1 must be allocated in a multiple of 2
sectors; on RAIDZ2 multiple of 3; and on RAIDZ3 multiple of 4. A sector
is a unit of 2^ashift bytes, typically 512B or 4KB.
To satisfy this constraint, the allocation size is rounded up to the
proper multiple, resulting in up to 3 "pad sectors" at the end of some
blocks. The contents of these pad sectors are not used, so we do not
need to read or write these sectors. However, some storage hardware
performs much worse (around 1/2 as fast) on mostly-contiguous writes
when there are small gaps of non-overwritten data between the writes.
Therefore, ZFS creates "optional" zio's when writing RAID-Z blocks that
include pad sectors. If writing a pad sector will fill the gap between
two (required) writes, we will issue the optional zio, thus doubling
performance. The gap-filling performance improvement was introduced in
July 2009.
Writing the optional zio is done by the io aggregation code in
vdev_queue.c. The problem is that it is also subject to the limit on
the size of aggregate writes, zfs_vdev_aggregation_limit, which is by
default 128KB. For a given block, if the amount of data plus padding
written to a leaf device exceeds zfs_vdev_aggregation_limit, the
optional zio will not be written, resulting in a ~2x performance
degradation.
The problem occurs only for certain values of ashift, compressed block
size, and RAID-Z configuration (number of parity and data disks). It
cannot occur with the default recordsize=128KB. If compression is
enabled, all configurations with recordsize=1MB or larger will be
impacted to some degree.
The problem notably occurs with recordsize=1MB, compression=off, with 10
disks in a RAIDZ2 or RAIDZ3 group (with 512B or 4KB sectors). Therefore
this problem has been known as "the 1MB 10-wide RAIDZ2 (or 3) problem".
The problem also occurs with the following configurations:
With recordsize=512KB or 256KB, compression=off, the problem occurs only
in rarely-used configurations:
* 4-wide RAIDZ1 with recordsize=512KB and ashift=12 (4KB sectors)
* 4-wide RAIDZ2 (either recordsize, either ashift)
* 5-wide RAIDZ2 with recordsize=512KB (either ashift)
* 6-wide RAIDZ2 with recordsize=512KB (either ashift)
With recordsize=1MB, compression=off, ashift=9 (512B sectors)
* RAIDZ1 with 4 or 8 disks
* RAIDZ2 with 4, 8, or 10 disks
* RAIDZ3 with 6, 8, 9, or 10 disks
With recordsize=1MB, compression=off, ashift=12 (4KB sectors)
* RAIDZ1 with 7 or 8 disks
* RAIDZ2 with 4, 5, or 10 disks
* RAIDZ3 with 6, 9, or 10 disks
With recordsize=2MB and larger (which can only be selected by changing
kernel tunables), many configurations are affected, including with
higher numbers of disks (up to 18 disks with recordsize=2MB).
Increase zfs_vdev_aggregation_limit to allow the optional zio to be
aggregated, thus eliminating the problem. Setting it to 256KB fixes all
commonly-used configurations.
The solution is to aggregate optional zio's regardless of the
aggregation size limit.

When a member of a RAIDZ has been replaced with a device smaller than
the original, then the top level vdev can report its expand size as
16.0E.
The reduced child asize causes the RAIDZ to have a vdev_asize lower than
its vdev_max_asize which then results in an underflow during the
calculation of the parents expand size.
Fix this by updating the vdev_asize if it shrinks, which is already
protected by a check against vdev_min_asize so should always be safe.
Also for RAIDZ vdevs, ensure that the sum of their child vdev_min_asize
is always greater than the parents vdev_min_size.

Closes#5943
In glibc 2.5, makedev(), major(), and minor() are defined in
sys/sysmacros.h. They are also defined in types.h for backward
compatability, but using these definitions triggers a compile warning.
This breaks the ZFS build, as it builds with -Werror.
autoconf email threads indicate these macros may be defined in
sys/mkdev.h in some cases.
This commit adds configure checks to detect where makedev() is defined:
sys/sysmacros.h
sys/mkdev.h
It assumes major() and minor() are defined in the same place.
The libspl types.h then includes
sys/sysmacros.h (preferred) or
sys/mkdev.h (2nd choice)
if one of those defines makedev().
This is done before including the system types.h.
An alternative would be to remove uses of major, minor, and makedev,
instead comparing the st_dev returned from stat64. These configure
checks would then be unnecessary.
This change revealed that __NORETURN was being defined unnecessarily in
libspl/include/sys/sysmacros.h. That definition is removed.
The files in which __NORETURN are used all include types.h, and so all
will get the definition provided by feature_tests.h

df83110 added the ability to specify a custom "ashift" value from the command
line in 'zpool add' and 'zpool attach'. This commit adds additional checks to
the provided ashift to prevent invalid values from being used, which could
result in disastrous consequences for the whole pool.
Additionally provide ASHIFT_MAX and ASHIFT_MIN definitions in spa.h.

For historical reasons zfs_mknode() was written such that it could
never fail. This poses a problem for Linux since zfs_znode_alloc()
could potentually failure due to low memory. Handle this gracefully
by retrying zfs_znode_alloc() until it succeeds, direct reclaim
will eventually be able to allocate memory.
