Provide a common zfs_file_* interface which can be implemented on all
platforms to perform normal file access from either the kernel module
or the libzpool library.
This allows all non-portable vnode_t usage in the common code to be
replaced by the new portable zfs_file_t. The associated vnode and
kobj compatibility functions, types, and macros have been removed
from the SPL. Moving forward, vnodes should only be used in platform
specific code when provided by the native operating system.

The tst.terminate_by_signal test case may occasionally fail when
running in a less consistent virtual environment. For all observed
failures the process was terminated correctly but it took longer than
expected resulting in too many snapshot being created.
To minimize the likelyhood of this occuring increase the threshold
from 50 to 90 snapshots. The larger limit will still verifiy that
the channel program was correctly terminated early.

Reinstate the zpl_revalidate() functionality to resolve a regression
where dentries for open files during a rollback are not invalidated.
The unrelated functionality for automatically unmounting .zfs/snapshots
was not reverted. Nor was the addition of shrink_dcache_sb() to the
zfs_resume_fs() function.
This issue was not immediately caught by the CI because the test case
intended to catch it was included in the list of ZTS tests which may
occasionally fail for unrelated reasons. Remove all of the rollback
tests from this list to help identify the frequency of any spurious
failures.

get, and inherit). I did this when topics were either too short to
warrant their own file or so interrelated that a user would want to
refer between commands in the same file.
Corrected .Sx internal references to .Xr cross refs; lots of .Sx
references from when text was all in zfs.8 needed to be changed to
.Xr zfs-$SUBCOMMAND 8 cross references.
Divided subcommand list in zfs(8) into sections of related

Preserved ".Os Linux", `.Os` macro parsing behavior differs between
mandoc from the "BSD" mandoc package (available on Ubuntu) and man
from Ubuntu's man-db package, which calls groff to format the manpages.
Groff handles the `.Os` macro differently and wrongly, defaulting
it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of
getting the default from `uname`.
A future set of changes will introduce build-time preprocessing of
manpages for platform-specific documentation and can insert the
correct operating system name.
Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man
pages needed their own SEE ALSO sections pointing to related

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.

Periodic snapshots deferral solution introduces zfs_exit_fs function,

Negative dentries and stale inodes are solved by flushing the dcache
for the particular dataset on zfs_resume_fs call.

Before my ZIL space optimization few years ago 128KB writes were logged
as two 64KB+ records in two 128KB log blocks. After that change it
became ~127KB+/1KB+ in two 128KB log blocks to free space in the second
block for another record. Unfortunately in case of 128KB only writes,
when space in the second block remained unused, that change increased
write latency by unbalancing checksum computation and write times
between parallel threads. It also didn't help with SLOG space
efficiency in that case.
This change introduces new 68KB log block size, used for both writes
below 67KB and 128KB-sharp writes. Writes of 68-127KB are still using
one 128KB block to not increase processing overhead. Writes above
131KB are still using full 128KB blocks, since possible saving there
is small. Mixed loads will likely also fall back to previous 128KB,
since code uses maximum of the last 16 requested block sizes.

This change modifies some of the infrastructure for enabling the use of
the DTRACE_PROBE* macros, such that we can use tehm in the "spl" module.
Currently, when the DTRACE_PROBE* macros are used, they get expanded to
create new functions, and these dynamically generated functions become
part of the "zfs" module.
Since the "spl" module does not depend on the "zfs" module, the use of
DTRACE_PROBE* in the "spl" module would result in undefined symbols
being used in the "spl" module. Specifically, DTRACE_PROBE* would turn
into a function call, and the function being called would be a symbol
only contained in the "zfs" module; which results in a linker and/or
runtime error.
Thus, this change adds the necessary logic to the "spl" module, to
mirror the tracing functionality available to the "zfs" module. After
this change, we'll have a "trace_zfs.h" header file which defines the
probes available only to the "zfs" module, and a "trace_spl.h" header
file which defines the probes available only to the "spl" module.
