There is a typo in the ->show_options function for disable_ext_identify.
Fix it to match the spelling from the documentation.

The fill_zero() from fallocate() calls get_new_data_page() in which calls
reserve_new_block().
The reserve_new_block() should be covered by *DATA_NEW*, one of global locks.
And also, before getting the lock, we should check free sections by calling
f2fs_balance_fs().
If we break this rule, f2fs is able to face with out-of-control free space
management and fall into infinite loop like the following scenario as well.
[f2fs_sync_fs()] [fallocate()]
- write_checkpoint() - fill_zero()
- block_operations() - get_new_data_page()
: grab NODE_NEW - get_dnode_of_data()
: get locked dirty node page
- sync_node_pages()
: try to grab NODE_NEW for data allocation
: trylock and skip the dirty node page
: call sync_node_pages() repeatedly in order to flush all the dirty node
pages!
In order to avoid this, we should grab another global lock such as DATA_NEW
before calling get_new_data_page() in fill_zero().

This patch enhances the checkpoint routine to cope with IO errors.
Basically f2fs detects IO errors from end_io_write, and the errors are able to
be occurred during one of data, node, and meta page writes.
In the previous code, when an IO error is occurred during writes, f2fs sets a
flag, CP_ERROR_FLAG, in the raw ckeckpoint buffer which will be written to disk.
Afterwards, write_checkpoint() will check the flag and remount f2fs as a
read-only (ro) mode.
However, even once f2fs is remounted as a ro mode, dirty checkpoint pages are
freely able to be written to disk by flusher or kswapd in background.
In such a case, after cold reboot, f2fs would restore the checkpoint data having
CP_ERROR_FLAG, resulting in disabling write_checkpoint and remounting f2fs as
a ro mode again.
Therefore, let's prevent any checkpoint page (meta) writes once an IO error is
occurred, and remount f2fs as a ro mode right away at that moment.

This patch stores inode->i_rdev into on-disk inode structure.
Alun reported that:
aspire tmp # mount -t f2fs /dev/sdb mnt
aspire tmp # mknod mnt/sda1 b 8 1
aspire tmp # mknod mnt/null c 1 3
aspire tmp # mknod mnt/console c 5 1
aspire tmp # ls -l mnt
total 2
crw-r--r-- 1 root root 5, 1 Jan 22 18:44 console
crw-r--r-- 1 root root 1, 3 Jan 22 18:44 null
brw-r--r-- 1 root root 8, 1 Jan 22 18:44 sda1
aspire tmp # umount mnt
aspire tmp # mount -t f2fs /dev/sdb mnt
aspire tmp # ls -l mnt

crw-r--r-- 1 root root 0, 0 Jan 22 18:44 console
crw-r--r-- 1 root root 0, 0 Jan 22 18:44 null
brw-r--r-- 1 root root 0, 0 Jan 22 18:44 sda1
In this report, f2fs lost the major/minor numbers of device files after umount.
The reason was revealed that f2fs does not store the inode->i_rdev to the
on-disk inode data structure.
So, as the other file systems do, f2fs also stores i_rdev into the i_addr fields
in on-disk inode structure without any on-disk layout changes.
Note that, this bug is limited to device files made by mknod().

"Fix for 3.8 breakage introduced by "vfs: Allow unprivileged
manipulation of the mount namespace" - accessing mnt->mnt_ns is done
there without needed locking *and* without any real need.
Definite -stable fodder, fortunately not going too far back.
This is *not* all - there will be much bigger vfs pull request
tomorrow."

It's safe only under namespace_sem or vfsmount_lock; all places
in fs/namespace.c that want mnt->mnt_ns->user_ns actually want to use
current->nsproxy->mnt_ns->user_ns (note the calls of check_mnt() in
there).

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace and namespace infrastructure changes from Eric W Biederman:
"This set of changes starts with a few small enhnacements to the user
namespace. reboot support, allowing more arbitrary mappings, and
support for mounting devpts, ramfs, tmpfs, and mqueuefs as just the
user namespace root.
I do my best to document that if you care about limiting your
unprivileged users that when you have the user namespace support
enabled you will need to enable memory control groups.
There is a minor bug fix to prevent overflowing the stack if someone
creates way too many user namespaces.
The bulk of the changes are a continuation of the kuid/kgid push down
work through the filesystems. These changes make using uids and gids
typesafe which ensures that these filesystems are safe to use when
multiple user namespaces are in use. The filesystems converted for
3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The
changes for these filesystems were a little more involved so I split
the changes into smaller hopefully obviously correct changes.
XFS is the only filesystem that remains. I was hoping I could get
that in this release so that user namespace support would be enabled
with an allyesconfig or an allmodconfig but it looks like the xfs
changes need another couple of days before it they are ready."

The cifs protocol has a 64bit space for uids and gids, while linux
only supports a 32bit space today. Instead of silently truncating
64bit cifs ids, replace cifs ids that do not fit in the 32bit linux
id space with the default uid and gids for the cifs mount.

Change uid and gid in struct nfsd4_cb_sec to be of type kuid_t and
kgid_t.
In nfsd4_decode_cb_sec when reading uids and gids off the wire convert
them to kuids and kgids, and if they don't convert to valid kuids or
valid kuids ignore RPC_AUTH_UNIX and don't fill in any of the fields.

In struct nfs4_ace remove the member who and replace it with an
anonymous union holding who_uid and who_gid. Allowing typesafe
storage uids and gids.
Add a helper pace_gt for sorting posix_acl_entries.
In struct posix_user_ace_state to replace uid with a union
of kuid_t uid and kgid_t gid.
Remove all initializations of the deprecated posic_acl_entry
e_id field. Which is not present when user namespaces are enabled.
Split find_uid into two functions find_uid and find_gid that work
in a typesafe manner.
In nfs4xdr update nfsd4_encode_fattr to deal with the changes
in struct nfs4_ace.
Rewrite nfsd4_encode_name to take a kuid_t and a kgid_t instead
of a generic id and flag if it is a group or a uid. Replace
the group flag with a test for a valid gid.
Modify nfsd4_encode_user to take a kuid_t and call the modifed
nfsd4_encode_name.
Modify nfsd4_encode_group to take a kgid_t and call the modified
nfsd4_encode_name.
Modify nfsd4_encode_aclname to take an ace instead of taking the
fields of an ace broken out. This allows it to detect if the ace is
for a user or a group and to pass the appropriate value while still
being typesafe.

These trivial macros that don't currently do anything are the last

u32 and uid_t have the same size and semantics so this change

whos type is uid_t.

ncpfs does not natively support uids and gids so this conversion was
simply a matter of updating the the type of the mounteduid, the uid
and the gid on the superblock. Fixing the ioctls that read them,
updating the mount option parser and the mount option printer.

Where kuid_t values are compared use uid_eq and where kgid_t values

kuids and kgids with other types.

In set_dqblk it is an error to look at fdq->d_id or fdq->d_flags.
Userspace quota applications do not set these fields when calling
quotactl(Q_XSETQLIM,...), and the kernel does not set those fields
when quota_setquota calls set_dqblk.
gfs2 never looks at fdq->d_id or fdq->d_flags after checking
to see if they match the id and type supplied to set_dqblk.
No other linux filesystem in set_dqblk looks at either fdq->d_id
or fdq->d_flags.
Therefore remove these bogus checks from gfs2 and allow normal
quota setting applications to work.
