accb62aedc Change puffs from hashlist to vcache. 
- field "pa_nhashbuckets" of struct "puffs_kargs" becomes a no-op.

- Use (type, minor) as key.

05d075b3ae Add VOP_FALLOCATE and VOP_FDISCARD to every vnode ops table I can 
find.

The filesystem ones all call genfs_eopnotsupp - right now I am only
implementing the plumbing and we can implement fallocate and/or
fdiscard for files later.

The device ones call spec_fallocate (which is also genfs_eopnotsupp)
and spec_fdiscard, which dispatches to the device-level op.

The fifo ones all call vn_fifo_bypass, which also ends up being
EOPNOTSUPP.

8ee3c88d2b Limit the minimum size of a disk sector to 512 bytes, to prevent memory 
overflow on extremely low secsize. This normally conforms to the old standard
(for which there doesn't seem to be a clear spec). Since 2011, IDEMA's Advanced
Format standardizes it to 4k, so this change won't cause any trouble on
new devices.

Put the printf under DIAGNOSTIC temporarily to see if someone complains.

hannken
605674c009 Remove the hints "isodir" and "relocated" from cd9660_vget_internal() 
and always reread the directory entry by inumber.  For directories
the directory entry is always its "." entry.

Always read directories via the device vnode to prevent buffer cache
inconsistency.  Keep i_devvp as a hint for fstat(1) and friends and
always use im_devvp for reads.  No need to vref()/vrele() i_devvp.

The additional bread is either cached because cd9660_lookup() just
released the buffer or will be used in the near future when the
directory gets traversed during lookup.

2b6ec89863 The current implementation of vn_lock() is racy. Modification of 
the vnode operations vector for active vnodes is unsafe because it
is not known whether deadfs or the original file system will be
called.

- Pass down LK_RETRY to the lock operation (hint for deadfs only).

- Change deadfs lock operation to return ENOENT if LK_RETRY is unset.

- Change all other lock operations to check for dead vnode once
  the vnode is locked and unlock and return ENOENT in this case.

With these changes in place vnode lock operations will never succeed
after vclean() has marked the vnode as VI_XLOCK and before vclean()
has changed the operations vector.

1f5dbc945b tmpfs: replace the broken tmpfs_dircookie() logic which uses the node 
address truncated to 31 bits (required for 32-bit readdir compatibility,
e.g. linux32).  Instead, assign 2^31 range using the following logic:
- The first half of the 2^31 is assigned incrementally (the fast path).
- When exceeded, use the second half of 2^31, but manage with vmem(9).

It will require 2 billion files per-directory to trigger vmem(9) usage.
Also, while here, add some fixes for tmpfs_unmount().

Should fix PR/47739, PR/47480, PR/46088 and PR/41068.
Thanks to wiz@ for stress testing.

nfsv4 as well as new implementations of nfsv3 and nfsv2.

This import is from tonight's FreeBSD head and is unchanged from there
except for automated munging of rcsids, rearranging of paths, and an
autogenerated files.* file that might or might not be syntactically
valid. (I will check in the script that does this shortly.)

There is not the slightest chance this will configure yet, let alone
compile or run.
