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.

Currently, for certain sizes and classes of allocations we use
SPL caches that are backed by caches in the Linux Slab allocator
to reduce fragmentation and increase utilization of memory. The
way things are implemented for these caches as of now though is
that we don't keep any statistics of the allocations that we
make from these caches.
This patch enables the tracking of allocated objects in those
SPL caches by making the trade-off of grabbing the cache lock
at every object allocation and free to update the respective
counter.
Additionally, this patch makes those caches visible in the
/proc/spl/kmem/slab special file.
As a side note, enabling the specific counter for those caches
enables SDB to create a more user-friendly interface than
/proc/spl/kmem/slab that can also cross-reference data from
slabinfo. Here is for example the output of one of those
caches in SDB that outputs the name of the underlying Linux
cache, the memory of SPL objects allocated in that cache,
and the percentage of those objects compared to all the
objects in it:

Since 0.7.0, zpool import would unconditionally block on udev for 30
seconds. This introduced a regression in initramfs environments that
lack udev (particularly mdev based environments), yet use a zfs userland
tools intended for the system that had been built against udev. Gentoo's
genkernel is the main example, although custom user initramfs
environments would be similarly impacted unless special builds of the
ZFS userland utilities were done for them. Such environments already
have their own mechanisms for blocking until device nodes are ready
(such as genkernel's scandelay parameter), so it is unnecessary for
zpool import to block on a non-existent udev until a timeout is reached
inside of them.
Rather than trying to intelligently determine whether udev is available
on the system to avoid unnecessarily blocking in such environments, it
seems best to just allow the environment to override the timeout. I
propose that we add an environment variable called
ZPOOL_IMPORT_UDEV_TIMEOUT_MS. Setting it to 0 would restore the 0.6.x
behavior that was more desirable in mdev based initramfs environments.
This allows the system user land utilities to be reused when building
mdev-based initramfs archives.
