Page writebacks with WB_SYNC_NONE can take several seconds to complete
since they wait for the transaction group to close before being
committed. This is usually not a problem since the caller does not
need to wait. However, if we're simultaneously doing a writeback
with WB_SYNC_ALL (e.g via msync), the latter can block for several
seconds (up to zfs_txg_timeout) due to the active WB_SYNC_NONE
writeback since it needs to wait for the transaction to complete
and the PG_writeback bit to be cleared.
This commit deals with 2 cases:
- No page writeback is active. A WB_SYNC_ALL page writeback starts
and even completes. But when it's about to check if the PG_writeback
bit has been cleared, another writeback with WB_SYNC_NONE starts.
The sync page writeback ends up waiting for the non-sync page
writeback to complete.
- A page writeback with WB_SYNC_NONE is already active when a
WB_SYNC_ALL writeback starts. The WB_SYNC_ALL writeback ends up
waiting for the WB_SYNC_NONE writeback.
The fix works by carefully keeping track of active sync/non-sync
writebacks and committing when beneficial.

For draid vdevs it was possible to initiate both the
sequential and healing resilver at same time.
This fixes the following two scenarios.
1) There's a window where a sequential rebuild can
be started via ZED even if a healing resilver has been
scheduled.
- This is fixed by adding additional check in
spa_vdev_attach() for any scheduled resilver and return
appropriate error code when a resilver is already in
progress.
2) It was possible for zpool clear to start a healing
resilver when it wasn't needed at all. This occurs because
during a vdev_open() the device is presumed to be healthy not
until the device is validated by vdev_validate() and it's set
unavailable. However, by this point an async resilver will
have already been requested if the DTL isn't empty.
- This is fixed by cancelling the SPA_ASYNC_RESILVER
request immediately at the end of vdev_reopen() when a resilver
is unneeded.
Finally, added a testcase in ZTS for verification.

When a page is faulted in for memory mapped I/O the page lock
may be dropped before it has been read and marked up to date.
If a buffered read encounters such a page in mappedread() it
must wait until the page has been updated. Failure to do so
will result in a panic on debug builds and incorrect data on
production builds.
The critical part of this change is in mappedread() where pages
which are not up to date are now handled. Additionally, it
includes the following simplifications.
- zfs_getpage() and zfs_fillpage() could be passed an array of
pages. This could be more efficient if it was used but in
practice only a single page was ever provided. These
interfaces were simplified to acknowledge that.
- update_pages() was modified to correctly set the PG_error bit
on a page when it cannot be read by dmu_read().
- Setting PG_error and PG_uptodate was moved to zfs_fillpage()
from zpl_readpage_common(). This is consistent with the
handling in update_pages() and mappedread().
- Minor additional refactoring to comments and variable
declarations to improve readability.
- Add a test case to exercise concurrent buffered, direct,
and mmap IO to the same file.
- Reduce the mmap_sync test case default run time.

commit ee6bf97c77 upstream
mmapwrite spawns several threads, all of which perform writes on a file
for the purpose of testing the behavior of mmap(2)-ed files. One
thread performs an mmap and a write to the beginning of that region,
while the others perform regular writes after lseek(2)-ing the end of
the file.
Because these regular writes are set in a while (1) loop, they will
write an unbounded amount of data to disk. The mmap_write_001_pos test
script SIGKILLs them after 30 seconds, but on fast testbeds, this may
be enough time to exhaust the available space in the filesystem,
leading to spurious test failures.
Instead, limit the total file size by checking that the lseek return
value is no greater than 250 * 1024*1024 bytes, which is less than the
default minimum vdev size defined in includes/default.cfg .
This also includes part of 2a493a4c71,

Commit 68ddc06b61 introduced support
for receiving unencrypted datasets as children of encrypted ones but
unfortunately got the logic upside down. This resulted in failing to
deny receives of incremental sends into encrypted datasets without
their keys loaded. If receiving a filesystem, the receive was done
into a newly created unencrypted child dataset of the target. In
case of volumes the receive made the target volume undeletable since
a dataset was created below it, which we obviously can't handle.
Incremental streams with embedded blocks are affected as well.
We fix the broken logic to properly deny receives in such cases.

When iterating through children physical ashifts for vdev, prefer
ones above the maximum logical ashift, that we can actually use,
but within the administrator defined maximum.
When selecting top-level vdev ashift, do not set it to the defined
maximum in case physical ashift is even higher, but just ignore one.
Using the maximum does not prevent misaligned writes, but reduces
space efficiency. Since ZFS tries to write data sequentially and
aggregates the writes, in many cases large misanigned writes may be
not as bad as the space penalty otherwise.
Allow internal physical ashifts for vdevs higher than SHIFT_MAX.
May be one day allocator or aggregation could benefit from that.
Reduce zfs_vdev_max_auto_ashift default from 16 (64KB) to 14 (16KB),
so that ZFS may still use bigger ashifts up to SHIFT_MAX (64KB),
but only if it really has to or explicitly told to, but not as an
"optimization".
There are some read-intensive NVMe SSDs that report Preferred Write
Alignment of 64KB, and attempt to build RAIDZ2 of those leads to a
space inefficiency that can't be justified. Instead these changes
make ZFS fall back to logical ashift of 12 (4KB) by default and
only warn user that it may be suboptimal for performance.
