Commit https://github.com/torvalds/linux/commit/3d745ea5 simplified
the blk_alloc_queue() interface by updating it to take the request
queue as an argument. Add a wrapper function which accepts the new
arguments and internally uses the available interfaces.
Other minor changes include increasing the Linux-Maximum to 5.6 now
that 5.6 has been released. It was not bumped to 5.7 because this
release has not yet been finalized and is still subject to change.
Added local 'struct zvol_state_os *zso' variable to zvol_alloc.

Increase the minimum supported kernel version from 2.6.32 to 3.10.
This removes support for the following Linux enterprise distributions.
Distribution | Kernel | End of Life
---------------- | ------ | -------------
Ubuntu 12.04 LTS | 3.2 | Apr 28, 2017
SLES 11 | 3.0 | Mar 32, 2019
RHEL / CentOS 6 | 2.6.32 | Nov 30, 2020
The following changes were made as part of removing support.
* Updated `configure` to enforce a minimum kernel version as
specified in the META file (Linux-Minimum: 3.10).
configure: error:
*** Cannot build against kernel version 2.6.32.
*** The minimum supported kernel version is 3.10.
* Removed all `configure` kABI checks and matching C code for
interfaces which solely predate the Linux 3.10 kernel.
* Updated all `configure` kABI checks to fail when an interface is
missing which was in the 3.10 kernel up to the latest 5.1 kernel.
Removed the HAVE_* preprocessor defines for these checks and
updated the code to unconditionally use the verified interface.
* Inverted the detection logic in several kABI checks to match
the new interface as it appears in 3.10 and newer and not the
legacy interface.
* Consolidated the following checks in to individual files. Due
the large number of changes in the checks it made sense to handle
this now. It would be desirable to group other related checks in
the same fashion, but this as left as future work.
- config/kernel-blkdev.m4 - Block device kABI checks
- config/kernel-blk-queue.m4 - Block queue kABI checks
- config/kernel-bio.m4 - Bio interface kABI checks
* Removed the kABI checks for sops->nr_cached_objects() and
sops->free_cached_objects(). These interfaces are currently unused.

Closes#9566
Added support for the bops->check_events() interface which was
added in the 2.6.38 kernel to replace bops->media_changed().
Fully implementing this functionality allows the volume resize
code to rely on revalidate_disk(), which is the preferred
mechanism, and removes the need to use check_disk_size_change().
In order for bops->check_events() to lookup the zvol_state_t
stored in the disk->private_data the zvol_state_lock needs to
be held. Since the check events interface may poll the mutex
has been converted to a rwlock for better concurrently. The
rwlock need only be taken as a writer in the zvol_free() path
when disk->private_data is set to NULL.
The configure checks for the block_device_operations structure
were consolidated in a single kernel-block-device-operations.m4
file.
The ZFS_AC_KERNEL_BDEV_BLOCK_DEVICE_OPERATIONS configure checks
and assoicated dead code was removed. This interface was added
to the 2.6.28 kernel which predates the oldest supported 2.6.32
kernel and will therefore always be available.
Updated maximum Linux version in META file. The 4.17 kernel
was released on 2018-06-03 and ZoL is compatible with the
finalized kernel.

Add META tags Linux-Maximum and Linux-Minimum.
One pain point for package maintainers is ensuring the compatibility of
the packaged version of ZFS with the Linux kernel. By providing an
authoritative compatibility guide in the source tree, maintainers can
automate compatibility checks.
Additionally, increase META string extraction specificity.
configure.ac finds Name and Version by a very simple `grep`, which might
conceivably find other fields. Require the string be at the beginning of
a line, and be followed by a colon to avoid such confusions.

Issue #2757
Create the first 0.6.0 release candidate tag (rc1). The Posix
layer is now functional and passes fstest and several other
test suites cleanly. We now need this release candidate tag
to broaden the test coverage before we can release the official
zfs-0.6.0.
Add autoconf style build infrastructure to the ZFS tree. This
includes autogen.sh, configure.ac, m4 macros, some scripts/*,
and makefiles for all the core ZFS components.
