Linux kernel commit 0f00b82e5413571ed225ddbccad6882d7ea60bc7 removes the
revalidate_disk() handler from struct block_device_operations. This
caused a regression, and this commit eliminates the call to it and the
assignment in the block_device_operations static handler assignment
code, when configure identifies that the kernel doesn't support that
API handler.

When dRAID performs a normal read operation only the data columns
in the raid map are read from disk. This is enough information to
calculate the checksum, verify it, and return the needed data to the
application. It's only in the event of a checksum failure that the
additional parity and any empty columns must be read since they are
required for parity reconstruction.
Reading these additional columns is handled by vdev_raidz_read_all()
which calls vdev_draid_map_alloc_empty() to expand the raid_map_t
and submit IOs for the missing columns. This all works correctly,
but it fails to account for any "short" columns. These are data
columns which are padded with a empty skip sector at the end.
Since that empty sector is not needed for a normal read it's not
read when columns is first read from disk. However, like the parity
and empty columns the skip sector is needed to perform reconstruction.
The fix is to mark any "short" columns as never being read by clearing
the rc_tried flag when expanding the raid_map_t. This will cause
the entire column to re-read from disk in the event of a checksum
failure allowing the self-healing functionality to repair the block.
Note that this only effects the self-healing feature because when
scrubbing a pool the parity, data, and empty columns are all read
initially to verify their contents. Furthermore, only blocks which
contain "short" columns would be effected, and only when the memory
backing the skip sector wasn't already zeroed out.
This change extends the existing redundancy_raidz.ksh test case to
verify self-healing (as well as resilver and scrub). Then applies
the same test case to dRAID with a slightly modified version of
the test script called redundancy_draid.ksh. The unused variable
combrec was also removed from both test cases.

ZFS was not setting max_len in the case where the handle was too
small. As a result of this, the `t_name_to_handle_at.c' example in
name_to_handle_at(2) did not work on ZFS.
zfsctl_fid() will itself set max_len if called with a fid that is too
small, so if we give zfs_fid() that behavior as well, the fix is quite
easy: if the handle is too small, just use a zero-size fid instead of
the handle.
Tested by running t_name_to_handle_at on a normal file, a directory, a
.zfs directory, and a snapshot.

While OpenZFS does permit breaking changes to the libzfs API, we should
avoid these changes when reasonably possible, and take steps to mitigate
the impact to consumers when changes are necessary.
Commit e4288a8397 made a libzfs API change that is especially
difficult for consumers because there is no change to the function
signatures, only to their behavior. Therefore, consumers can't notice
that there was a change at compile time. Also, the API change was
incompletely and incorrectly documented.
The commit message mentions `zfs_get_prop()` [sic], but all callers of
`get_numeric_property()` are impacted: `zfs_prop_get()`,
`zfs_prop_get_numeric()`, and `zfs_prop_get_int()`.
`zfs_prop_get_int()` always calls `get_numeric_property(src=NULL)`, so
it assumes that the filesystem is not mounted. This means that e.g.
`zfs_prop_get_int(ZFS_PROP_MOUNTED)` always returns 0.
The documentation says that to preserve the previous behavior, callers
should initialize `*src=ZPROP_SRC_NONE`, and some callers were changed
to do that. However, the existing behavior is actually preserved by
initializing `*src=ZPROP_SRC_ALL`, not `NONE`.
The code comment above `zfs_prop_get()` says, "src: ... NULL will be
treated as ZPROP_SRC_ALL.". However, the code actually treats NULL as
ZPROP_SRC_NONE. i.e. `zfs_prop_get(src=NULL)` assumes that the
filesystem is not mounted.
There are several existing calls which use `src=NULL` which are impacted
by the API change, most noticeably those used by `zfs list`, which now
assumes that filesystems are not mounted. For example,
`zfs list -o name,mounted` previously indicated whether a filesystem was
mounted or not, but now it always (incorrectly) indicates that the
filesystem is not mounted (`MOUNTED: no`). Similarly, properties that
are set at mount time are ignored. E.g. `zfs list -o name,atime` may
display an incorrect value if it was set at mount time.
To address these problems, this commit reverts commit e4288a8397bb1f:
"zfs get: don't lookup mount options when using "-s local""

This ensures that we don't accumulate checksum errors against offline or
unavailable devices but, more importantly, means that we don't
needlessly create DTL entries for offline devices that are already
up-to-date.
Consider a 3-way mirror, with disk A always online (and so always with
an empty DTL) and B and C only occasionally online. When A & B resilver
with C offline, B's DTL will effectively be appended to C's due to these
spurious ZIOs even as the resilver empties B's DTL:
* These ZIOs land in vdev_mirror_scrub_done() and flag an error
* That flagged error causes vdev_mirror_io_done() to see
unexpected_errors, so it issues a ZIO_TYPE_WRITE repair ZIO, which
inherits ZIO_FLAG_SCAN_THREAD because zio_vdev_child_io() includes
that flag in ZIO_VDEV_CHILD_FLAGS.
* That ZIO fails, too, and eventually zio_done() gets its hands on it
and calls vdev_stat_update().
* vdev_stat_update() sees the error and this zio...
* is not speculative,
* is not due to EIO (but rather ENXIO, since the device is closed)
* has an ->io_vd != NULL (specifically, the offline leaf device)
* is a write
* is for a txg != 0 (but rather the read block's physical birth txg)
* has ZIO_FLAG_SCAN_THREAD asserted
* So: vdev_stat_update() calls vdev_dtl_dirty() on the offline vdev.
Then, when A & C resilver with B offline, that story gets replayed and
C's DTL will be appended to B's.
In fact, one does not need this permanently-broken-mirror scenario to
induce badness: breaking a mirror with no DTLs and then scrubbing will
create DTLs for all offline devices. These DTLs will persist until the
entire mirror is reassembled for the duration of the *resilver*, which,
incidentally, will not consider the devices with good data to be sources
of good data in the case of a read failure.
