2b280fab12 [CIFS] add more complete mount options to cifs_show_options
adds various options to cifs_show_options
(displayed when you cat /proc/mounts with a cifs mount).  I limited
the new ones to values that are associated with the mount with the
exception of "seal" (which is a per tree connection property, but I
thought was important enough to show through).

Eventually cifs's parse_mount_options also needs to
be rewritten to use the match_token API but that would be a big enough
change that I would prefer that changing parse_mount_options wait
until next release.

e9baf6e598 [PATCH] return to old errno choice in mkdir() et.al.
In case when both EEXIST and EROFS would apply we used to
return the former in mkdir(2) and friends.  Lest anyone suspects
us of being consistent, in the same situation knfsd gave clients
nfs_erofs...

	ro-bind series had switched the syscall side of things to
returning -EROFS and immediately broke an application - namely,
mkdir -p.  Patch restores the original behaviour...

adbecb128c [PATCH] dup_fd() part 4 - race fix
Parent _can_ be a clone task, contrary to the comment.  Moreover,
more files could be opened while we allocate a copy, in which case
we end up copying only part into new descriptor table.  Since what
we get _is_ affected by all changes in the old range, we can get
rather weird effects - e.g.
	dup2(0, 1024); close(0);
in parallel with fork() resulting in child that sees the effect of
close(), but not that of dup2() done just before that close().

What we need is to recalculate the open_count after having reacquired
->file_lock and if external fdtable we'd just allocated is too small for
it, free the sucker and redo allocation.

46c8ac7425 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.

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

b0b539739f 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.

0599ad53fe sysfs: remove error messages for -EEXIST case
It is possible that the entry in sysfs already exists, one case of this is
when a network device is renamed to bonding_masters. Anyway, in this case
the proper error path is for device_rename to return an error code, not to
generate bogus backtrace and errors.

Also, to avoid possible races, the create link should be done before the
remove link. This makes a device rename atomic operation like other renames.
