* We shouldn't truncate the file.
* We were leaving the vnode locked (unless the truncate happened to fail).
Solaris clients may cause this under some conditions.
Problem reported by chopps, analysis and fix by me.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
directory cookie that may be thrown back at us from userspace, up
to a size limit. Fixes double entry problem.
* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
value of 8k.
* Various other things that I forget, all related to the dir caching
somehow, though.
From Olaf Seibert <rhialto@polder.ubc.kun.nl> (PR 3687)
* Make an attempt to check the maximum filesize before attempting
a write to the server, as write RPCs will typically happen
asynchronously, and the process will not see the error.
Fixes problems with unexpectly truncated files at 4G
* Pass up errors in nfs_writerpc correctly
the server code would always skip all dir entries for a readdirplus
operation. To avoid endlessly retrying clients, try VFS_VGET first,
and it it fails, return NFSERR_NOTSUPP so that client will fall
back to normal readdir operations.
a request on the public filehandle. Extend the lookup operation to
support WebNFS, including index file support (URL style). Yucky, it's
optional in the spec, but Solaris 2.6 will support it, so..

In nfsrv_access(), if VOP_ACCESS() returns an error and the
error == EPERM or its not the owner doing the access, return the error.
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
cleanup.
* Require the file system to decide whether or not linking and unlinking of
directories is allowed, and disable it for all current file systems.
(Also, remove the cross-device link check, that was moved into the file
systems some time ago.)
