the ioff argument to pool_init() is unused and has been for many
years, so this replaces it with an ipl argument. because the ipl
will be set on init we no longer need pool_setipl.
most of these changes have been done with coccinelle using the spatch
below. cocci sucks at formatting code though, so i fixed that by hand.
the manpage and subr_pool.c bits i did myself.

trivial change to use rrw locks instead. All it needs is LK_* defines
for the RW_* flags.

usb stack was busy, the kernel could trigger an uvm fault. There
is a race between vop_generic_revoke() and sys_mount() where vgonel()
could reset v_specinfo. Then v_specmountpoint is no longer valid.
So after sleeping, msdosfs_mountfs() could crash in the error path.
The code in the different *_mountfs() functions was inconsistent,
implement the same check everywhere.

msdosfs and nfsv2 don't set f_namemax. ntfs and ext2fs don't set
f_namemeax and f_favail. fusefs doesn't set f_mntfromspec, f_favail and
f_iosize. Also, make all filesystems use copy_statfs_info(), so that all
statfs information is filled in correctly for the (sb != &mp->mnt-stat)
case.

could end up in an inconsistent state. The fstype dependent
mp->mnt_data was NULL, but the general mp was still listed as a
valid mount point. Next access to the file system would crash with
a NULL pointer dereference.
If closing the device fails, the mount point must go away anyway.
There is nothing we can do about it. Remove the workaround for the
EIO error in the general unmount code, but do not generate any error
in the file system specific unmount functions.

- rename uiomove() to uiomovei() and update all its users.
- introduce uiomove(), which is similar to uiomovei() but with a size_t.
- rewrite uiomovei() as an uiomove() wrapper.

objective: vnode.h doesn't include uvm_extern.h anymore.
followup changes: include uvm_extern.h or lock.h where necessary.

not returned instead of the offset after that one.
udf_uiodir() returns -1 when there isn't enough space for the next entry,
so just break from the loop and return 0 in that case.
Remove the bogus printf there now that this is handled correctly.

members to 64bit types. Assign new syscall numbers for (almost
all) the syscalls that involve the affected types, including anything
with time_t, timeval, itimerval, timespec, rusage, dirent, stat,
or kevent arguments. Add a d_off member to struct dirent and replace
getdirentries() with getdents(), thus immensely simplifying and
accelerating telldir/seekdir. Build perl with -DBIG_TIME.
Bump the major on every single base library: the compat bits included
here are only good enough to make the transition; the T32 compat
option will be burned as soon as we've reached the new world are
are happy with the snapshots for all architectures.
DANGER: ABI incompatibility. Updating to this kernel requires extra
work or you won't be able to login: install a snapshot instead.

the special provided when the mount was requested. This may be the same as
the special that was actually used for the mount (e.g. in the case of a
device node) or it may be different (e.g. in the case of a DUID).
Whilst here, change f_ctime to a 64 bit type and remove the pointless
f_spare members.

_PC_PRIO_IO, and _PC_SYNC_IO names in VOP_PATHCONF(), as they're
fs-independent for us. Since we don't support latter three on any
fs, we can also define the related _POSIX_{ASYNC,PRIO,SYNC}_IO
symbols in <unistd.h> (via sys/unistd.h) with value -1.
Also, zap pointless tty-only values from procfs(!).

- Avoid using copyinstr() without checking the return value.
- sys_mount() has already copied the path in, so pass this to the
filesystem mount code so that it does not have to copy it in again.
- Avoid copyinstr()/bzero() dance when we can simply bzero() and strlcpy().

are past. Use CLR() and SET() to modify necessary flags while leaving
the flags used by the buffer cache in peace.
Should make bufcache code much less confused about the state of the
bufs used in reading/writing disklabels. Other such flag abuses no
doubt await a visit.

Filesystems should, at some point fill in every function
in the vop_default struct so we can get rid of the 'if'
statements in VOP_*.

vector setup that has questionable features (that have, as far as I can
tell never been used in practice, atleast not in OpenBSD), remove all
the gunk and favor a simple struct full of function pointers that get
set directly by each of the filesystems.
Removes gobs of ugly code and makes things simpler by a magnitude.
The only downside of this is that we loose the vnoperate feature so
the spec/fifo operations of the filesystems need to be kept in sync
with specfs and fifofs, this is no big deal as the API it self is pretty
static.
Many thanks to armani@ who pulled an earlier version of this diff to
current after c2k10 and Gabriel Kihlman on tech@ for testing.
