The following set of patches fix known issues with the 2.6.26-rc2 NFS client
code, and significantly enhance the support for NFSv4.

NFS: Ensure that 'noac' and/or 'actimeo=0' turn off attribute caching
Both the 'noac' and 'actimeo=0' mount options should ensure that attributes are not
cached, however a bug in nfs_attribute_timeout() means that currently, the attributes
may in fact get cached for up to one jiffy. This has been seen to cause corruption in
some applications.
The reason for the bug is that the time_in_range() test returns 'true' as long as
the current time lies between nfsi->read_cache_jiffies and
nfsi->read_cache_jiffies + nfsi->attrtimeo. In other words, if jiffies equals
nfsi->read_cache_jiffies, then we still cache the attribute data.

nfs: fix race in nfs_dirty_request
When called from nfs_flush_incompatible, the req is not locked, so req->wb_page
might be set to NULL before it is used by PageWriteback.

NFSv4: Check the return value of decode_compound_hdr_arg()
If decode_compound_hdr_arg() returns a resource error, then we cannot proceed to
process the callback. Return a 'GARBAGE_ARGS' rpc-level error to the caller instead.
If, however, the minor version field is incorrect, then we need to propagate the
resulting NFS4ERR_MINOR_VERS_MISMATCH error back as the compound status field (setting
the nops field to 0).
Finally, if encode_compound_hdr_res() returns an error, we need to return an
RPC_SYSTEM_ERR to the caller.

nfs/lsm: make NFSv4 set LSM mount options
NFSv3 get_sb operations call into the LSM layer to set security options passed from
userspace. NFSv4 hooks were not originally added since it was reasonably late in the
merge window and NFSv3 was the only thing that had regressed (v4 has never supported
any LSM options)
This patch makes NFSv4 call into the LSM to set security options rather than just
blindly dropping them with no notice to the user as happens today. This patch was
tested in a simple NFSv4 environment with the context= option and appeared to work as
expected.
