g_raid3.h 1.12
Use root_mount KPI for RAID3 to delay root file system mount.
Actually, one cannot setup root file system on RAID3 device, but when
other file system exist in /etc/fstab which are placed on RAID3 device,
boot process will be interrupted when these devices are missing.

Before calling g_orphan_provider(), add G_PF_WITHER flag, so GEOM will know
to destroy it.

post an event to the geom event queue that will take care of it,
letting outstanding bios finish, and closing the consumers.
Plus some cosmetic clean ups.
resides on. Fix the special case of the filesystem fragment size not
evenly dividing the size of the provider. Fixing the general case
probably requires better superblock validation (left as an exercise to
the reader).
While we wait for holds to be released, print a list of who holds us
back once per second.
Use the new KPI from GEOM instead of vfs_mount.c calling g_waitidle().
Use the new KPI also from ata.
With ATAmkIII's newbusification, ata could narrowly miss the window
and ad0 would not exist when we tried to mount root.
in BSD and MBR classes, ie. if provider below us uses the same metadata,
don't create labels based on the metadata.
This allows to create labels on geoms with rank != 1 without hacks.

shared-last-sector problem.
After this change, even if there is more than one provider with the same
last sector, the proper one will be chosen based on its size.
It still doesn't fix the 'c' partition problem (when da0s1 can be confused
with da0s1c) and situation when 'a' partition starts at offset 0
(then da0s1a can be confused with da0s1 and da0s1c). One can use '-h'
option there, when creating device or avoid sharing last sector.
Actually, when providers share the same last sector and their size is equal,
they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c)
isn't important at all.

patch from kan@).
Pull bufobj_invalbuf() out of vinvalbuf() and make g_vfs call it on
close. This is not yet a generally safe function, but for this very
specific use it is safe. This solves the problem with buffers not
being flushed by unmount or after failed mount attempts.
This flag means "wait for all pending requests before returning to userland".
There are pending events for sure, because we just created new provider and
other classes want to taste it, but we cannot answer on I/O requests until
we're here.
