e10a32f7f7 Remove miscfs/syncfs and 
- move the syncer into kern/vfs_subr.c.

- change the syncer to process the mountlist and VFS_SYNC as appropriate.

- use an API for mount points similiar to the API for vnodes:
  - vfs_syncer_add_to_worklist(struct mount *mp) to add
  - vfs_syncer_remove_from_worklist(struct mount *mp) to remove a mount.

No objections on tech-kern@

d02097e5a9 Update file size after write without metadata flush 
If we do not use metadata flush, we must make sure the size is updated
in the filesystem after a write, otherwise the next GETATTR will get us
a stale value and the file will be truncated.

may be NULL and may change any time.

8abab6b782 Add PUFFS_KFLAG_NOFLUSH_META to prevent sending metadata flush to FUSE 
FUSE filesystems do not expect to get metadata updates for [amc]time
and size, they updates the value on their own after operations.

The PUFFS PUFFS_KFLAG_NOFLUSH_META option prevents regular metadata cache
flushes to the filesystem , and libperfuse uses it to match Linux FUSE
behavior.

While there, fix a bug in SETATTR: do not update kernel metadata cache
from SETATTR reply when the request is asynchronous, as we do not have
the reply yet.

40e39321ca Revert previous, it was a false positive. 
In nilfs_mount_device() there's one branch where the node is not released:
when the device is already mounted. Not releasing it was thus intentional,
but this is something code scanners can't understand.

acbabd6a6a When udf_symlink() fails, do not explicitly call udf_delete_node(), as 
vrele() called next will do that again - avoids a double free of the
bitmap, leading to a KASSERT failure (or worse in real life) in the
udf_symlink_long in the fs/vfs::t_vnops test.

5fc94787c1 Make sure reads on empty files reach PUFFS filesystems 
Sending a read through the page cache will get the operation
short-circuited. This is a problem with some filesystems that
expect to receive the read operation in order to update atime.

We fix that by bypassing the page cache when reading a file
wich a size known to be zero.

c182898b0d We have three sets of DTYPE_ constants in the kernel: 
altq		Drop 		Type
	disklabel	Disk 		Type
	file		Descriptor	Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.

6a89606711 I started to KNF this file but quickly ended up figuring out I was not

lines.
