table lock

Whoever did the strsep patches didn't check that ips still compiles.
here's a patch.

Found a few typos in the input changes. Fixup patch attached.

  drivers/ide/probe.c initializes gd->de_arr and gd->flags twice. Except that
it is unnecessary it also leaks memory.

Edition 4.1 of the System V Application Binary Interface says that
"The first namesz bytes in name contains a null-terminated
representation of the entry's owner or originator".  This implies that
the terminating null is included in namesz, which is corroborated by
the example that follows the description.  However, this is not what
the Linux kernel does when it writes its notes into an ELF core dump.
The attached patch fixes this.

HACK ALERT! This needs to be fixed to do what reiserfs
actually thinks it _should_ do.

In usb_bluetooth_probe, the transfer buffers for the write pool urbs
are allocated with size 0, because bluetooth->bulk_out_buffer_size isn't set
until after the loop.

Moved the file ops and minor number stuff out of the usb structure,
Now usb_register_dev() and usb_deregister_dev() must be called if 
you want to use the USB major number.

This patch removes BKL protection from the invocation of the
super_operations ->statfs() method, and shifts it into the filesystems
where necessary. Any out-of-tree filesystems may need to take the BKL in
their statfs() methods if they were relying on it for synchronisation.

All ->statfs() implementations have been modified to take the BKL,
except for those that don't reference any external mutable data or that
already have their own locking.

Additionally, capifs is changed to use simple_statfs rather than its
own home-grown version.

The BKL change has been flagged at the end of
Documentation/filesystems/porting, along with the recent change to
->permission BKL usage.

I chose a little bit more restrictive license for my drivers.
Rx skb pool introduced in pegasus driver and the pool locking in rtl8150
is refined.

	* ->i_dev followed the example of ->s_dev - it's dev_t now.  All
remaining uses of ->i_dev either outright want dev_t (stat()) or couldn't
care less (printing major:minor in /proc/<pid>/maps, etc.)

	* JFS uses its ->logdev only twice - one of the places assigns
it to_kdev_t(le32_to_cpu(...)), another uses kdev_t_to_nr() of it.
Switched to u32 - it's just a place where we store device number we'd got
from superblock.
	* several reiserfs_fs.h function prototypes removed - functions
in question don't exist anymore.
	* smbfs doesn't support device nodes; ->f_rdev removed.

	* svc_export ->ex_dev turned into dev_t.  It's a pure search
key and all places that set it actually do to_kdev_t(some_dev_t_expression).

	* ->dev killed for md/linear.c (same as previous parts)

	* md_import_device() returns resulting rdev or ERR_PTR(error)
instead of returning 0 or error an letting caller find rdev.

	* a bunch of callers of partition_name() are calling
bdev_partition_name(),
	* the last users of raid1 and multipath ->dev are gone; so are
the fields in question.

	* ->diskop() split into individual methods; prototypes cleaned
up.  In particular, handling of hot_add_disk() gets mdk_rdev_t * of
the component we are adding as an argument instead of playing the games
with major/minor.  Code cleaned up.

	* ->error_handler() switched to struct block_device *.
	* md_sync_acct() switched to struct block_device *.
	* raid5 struct disk_info ->dev is gone - we use ->bdev everywhere.
	* bunch of kdev_same() when we have corresponding struct block_device *
and can simply compare them is removed from drivers/md/*.c

	* since the last caller of is_read_only() is gone, the function
itself is removed.
	* destroy_buffers() is not used anymore; gone.
	* fsync_dev() is gone; the only user is (broken) lvm.c and first
step in fixing lvm.c will consist of propagating struct block_device *
anyway; at that point we'll just use fsync_bdev() in there.
	* prototype of bio_ioctl() removed - function doesn't exist
anymore.

	* Bunch of functions in cdrom.c used to get kdev_t and use it
only to do cdrom_find_device(dev), even though their callers already
had struct cdrom_device_info * in question.  Switched to passing
said pointer directly.
	* useless exports removed; stuff not used outside of cdrom.c
made static.

	* calc_dev_sboffset() and calc_dev_size() in md.c are getting
mk_rdev_t instead of kdev_t.  Callers updated.
	* calls of blkdev_size_in_bytes() in md.c replaced with use
of rdev->bdev->bd_inode->i_size.

	* devpts "upcalls" eliminated.
	* instead of playing games with revalidation we simply use
ramfs-style tree and kill dentries upon devpts_pty_kill().  That
allows to get rid of a lot of code in fs/devpts/*.c.
	* devpts_fs.h cleaned up.
	* devpts/root.c and devpts/devpts_i.h removed.
	* array of pointers to devpts inodes killed; with ramfs-style tree
it's not needed anymore.
	* devpts/inode.c cleaned up.
	* devpts_pty_new() used to get mk_kdev() only to convert it to
dev_t (hardly a surprise, since it's mknod() in disguise).  Now it gets
dev_t as an argument.

This is Bill Irwin's cleanup patch which gives symbolic names to the
fault types:

	#define VM_FAULT_OOM	(-1)
	#define VM_FAULT_SIGBUS	0
	#define VM_FAULT_MINOR	1
	#define VM_FAULT_MAJOR	2

Only arch/i386 has been updated - other architectures can do this too.

The blockdev mapping's private_lock is fairly contended.  The buffer
LRU cache fixed a lot of that, but under page replacement load,
try_to_free_buffers is still showing up.

Moving the freeing of buffer_heads outside the lock reduces contention
in there by 30%.
