NTFS: Fix a nasty deadlock that appeared in recent kernels.
The situation: VFS inode X on a mounted ntfs volume is dirty. For
same inode X, the ntfs_inode is dirty and thus corresponding on-disk
inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging
to the table of inodes, i.e. $MFT, inode 0.
What happens:
Process 1: sys_sync()/umount()/whatever... calls
__sync_single_inode() for $MFT -> do_writepages() -> write_page for
the dirty page containing the on-disk inode X, the page is now locked
-> ntfs_write_mst_block() which clears PageUptodate() on the page to
prevent anyone else getting hold of it whilst it does the write out.
This is necessary as the on-disk inode needs "fixups" applied before
the write to disk which are removed again after the write and
PageUptodate is then set again. It then analyses the page looking
for dirty on-disk inodes and when it finds one it calls
ntfs_may_write_mft_record() to see if it is safe to write this
on-disk inode. This then calls ilookup5() to check if the
corresponding VFS inode is in icache(). This in turn calls ifind()
which waits on the inode lock via wait_on_inode whilst holding the
global inode_lock.
Process 2: pdflush results in a call to __sync_single_inode for the
same VFS inode X on the ntfs volume. This locks the inode (I_LOCK)
then calls write-inode -> ntfs_write_inode -> map_mft_record() ->
read_cache_page() for the page (in page cache of table of inodes
$MFT, inode 0) containing the on-disk inode. This page has
PageUptodate() clear because of Process 1 (see above) so
read_cache_page() blocks when it tries to take the page lock for the
page so it can call ntfs_read_page().
Thus Process 1 is holding the page lock on the page containing the
on-disk inode X and it is waiting on the inode X to be unlocked in
ifind() so it can write the page out and then unlock the page.
And Process 2 is holding the inode lock on inode X and is waiting for
the page to be unlocked so it can call ntfs_readpage() or discover
that Process 1 set PageUptodate() again and use the page.
Thus we have a deadlock due to ifind() waiting on the inode lock.
The solution: The fix is to use the newly introduced
ilookup5_nowait() which does not wait on the inode's lock and hence
avoids the deadlock. This is safe as we do not care about the VFS
inode and only use the fact that it is in the VFS inode cache and the
fact that the vfs and ntfs inodes are one struct in memory to find
the ntfs inode in memory if present. Also, the ntfs inode has its
own locking so it does not matter if the vfs inode is locked.

[PATCH] modules: add version and srcversion to sysfs
This patch adds version and srcversion files to
/sys/module/${modulename} containing the version and srcversion fields
of the module's modinfo section (if present).
/sys/module/e1000
|-- srcversion
`-- version
This patch differs slightly from the version posted in January, as it
now uses the new kstrdup() call in -mm.
Why put this in sysfs?
a) Tools like DKMS, which deal with changing out individual kernel
modules without replacing the whole kernel, can behave smarter if they
can tell the version of a given module. The autoinstaller feature, for
example, which determines if your system has a "good" version of a
driver (i.e. if the one provided by DKMS has a newer verson than that
provided by the kernel package installed), and to automatically compile
and install a newer version if DKMS has it but your kernel doesn't yet
have that version.
b) Because sysadmins manually, or with tools like DKMS, can switch out
modules on the file system, you can't count on 'modinfo foo.ko', which
looks at /lib/modules/${kernelver}/... actually matching what is loaded
into the kernel already. Hence asking sysfs for this.
c) as the unbind-driver-from-device work takes shape, it will be
possible to rebind a driver that's built-in (no .ko to modinfo for the
version) to a newly loaded module. sysfs will have the
currently-built-in version info, for comparison.
d) tech support scripts can then easily grab the version info for what's
running presently - a question I get often.
There has been renewed interest in this patch on linux-scsi by driver
authors.
As the idea originated from GregKH, I leave his Signed-off-by: intact,
though the implementation is nearly completely new. Compiled and run on
x86 and x86_64.

[PATCH] knfsd: nfsd4: initialize recovery directory
NFSv4 clients are required to know what state they have on the server so that
they can reclaim it on server reboot. However, it is possible for
pathalogical combinations of server reboots and network partitions to leave a
client in a state where it cannot know whether it has lost its state on the
server.
For this reason, rfc3530 requires that we store some information about clients
to stable storage.
So we maintain a directory /var/lib/nfs/v4recovery with a subdirectory for
each client with active state. We leave open the possibility of including
files underneath each such subdirectory with information about the client, but
for now the subdirectories are empty.
We create a client subdirectory whenever a client makes its first non-reclaim
open_confirm.
We remove a client subdirectory whenever either
a) its lease expires, or
b) the grace period ends without it reclaiming anything.
When handling reclaims, we allow the reclaim if and only if the client doing
the reclaim has a subdirectory.
This patch adds just the code to scan the recovery directory on nfsd startup.

client might want to use the same lockowner string on multiple files, so we may
as well allow that. We expect each use of open_to_lockowner to create a

For now, let's just keep this simple, and wait till the next time nfsd starts

change the lease time *now*, they can go ahead and bring nfsd down and then
back up again after changing the lease time.

While we're at it, the slab code keeps statistics that help catch leaks and
such, so we may as well take this chance to eliminate some debugging counters
that we've been keeping ourselves.

[PATCH] nfsd4: block metadata ops during grace period
We currently return err_grace if a user attempts a non-reclaim open during the
grace period. But we also need to prevent renames and removes, at least, to
ensure clients have the chance to recover state on files before they are moved
or deleted.
Of course, local users could also do renames and removes during the lease
period, and there's not much we can do about that. This at least will help
with remote users.

[PATCH] nfsd4: fix fh_expire_type
We're returning NFS4_FH_NOEXPIRE_WITH_OPEN | NFS4_FH_VOL_RENAME for the
fh_expire_type attribute. This is incorrect:
1. The spec actually only allows NOEXPIRE_WITH_OPEN when
VOLATILE_ANY is also set.
2. Filehandles for open files can expire, if the file is removed
and there is a reboot.
3. Filehandles are only volatile on rename in the nosubtree check
case.
Unfortunately, there's no way to indicate that we only expire on remove. So
our only choice is FH4_VOLATILE_ANY. Although it's redundant, we also set
FH4_VOL_RENAME in the subtree check case, since subtreecheck does actually
cause problems in practice and it seems possibly useful to give clients some
way to distinguish that case.
Fix a mispelled #define while we're at it.
