Instead of spinning in a tight loop for up to 15 seconds, polling for device
readiness while it spins up, return reset completion just after PHY reports
"connect well" or 100ms connection timeout. If device was found, use callout
for checking device readiness with 100ms period up to full 31 second timeout.
This fixes system freeze for 5-10 seconds on drives hot plug-in.
embedded flash stores.
Some devices - notably those with uboot - don't have an
explicit partition table (eg like Redboot's FIS.)
geom_map thus provides an easy way to export the hard-coded
flash layout as geom providers for use by filesystems and
other tools.
It also includes a "search" function which allows for
dynamic creation of partition layouts where the device only
has a single hard-coded partition. For example, if
there is a "kernel+rootfs" partition, a single image can
be created which appends the rootfs after the kernel with
an appropriate search string. geom_map can be told to
search for said search string and create a partition
beginning after it.

CHECK_TIME actually triggers thinking param.h is in the future (see f_Xtime,
c_Xtime logi in find(1) sources for the details in !F_EXACTTIME case).
Using the -mtime -0s (seconds, rather than no unit) avoids this 1s race.

a one of the ways to report error for CBI devices.

negative return value from write to update its position in
a buffer. The patch, courtesy of Andrey Simonenko, also simplifies
a conditional by removing the "i != cnt" clause, since it is
always true at this point in the code. The bug caused problems
for mountd, when it generated a large reply to an exports RPC
request.

- Keep a hash of indirect blocks that have recently been freed and are
still referenced in the journal.
- Lookup blocks in this hash before forcing a new block write to wait on
the journal entry to hit the disk. This is only necessary to avoid
confusion between old identities as indirects and new identities as
file blocks.
- Don't free jseg structures until the journal has written a record that
invalidates it. This keeps the indirect block information around for
as long as is required to be safe.
- Force an empty journal block write when required to flush out stale
journal data that is simply waiting for the oldest valid sequence
number to advance beyond it.
