 - add lo->lo_blocksize
 - kill lo_get_bs() - great name, but...
 - set ->lo_device only if we do have a block device
 - pull determination of ->lo_blocksize into both branches - bdev
   variant gets it from lo_device and file one uses ->i_blocksize.
 - switched the ioctl getting information about underlying object
   to lo->lo_device ? stat.rdev : stat.dev
 - i.e. st_rdev of underlying object if it's a device and st_dev - if it's
   a file.
 - reverted the bogosity in shmem.c

Patch from Hugh Dickins

Added shmem_readpage and shmem_prepare_write so tmpfs files can be used
by the loop driver (together with simple_commit_write).  shmem_getpage
extended to accept file page passed in, which may have to be copied
over from swap page.

Use bdget and sb_set_blocksize so loop can see our preferred blocksize
PAGE_CACHE_SIZE.  Use copy_highpage, removed from highmem.h in 2.4.17:
restore it but with kmap_atomics.  Restore (a simple) copy_page to
asm-sparc64/page.h, which alone of all arches discarded it.

Patch from Hugh Dickins

From Matthew Wilcox <willy@debian.org>: shmem_getpage must
flush_dcache_page after allocating and clearing a new page.

Patch from Hugh Dickins

Checked shmem_file_write against recent filemap source, and against
2.4 and 2.4-ac: folded in missing fixes, mostly related to far file
positions.  Plus the new kmap_atomic copying technique.  But for now,
as before, no mark_page_accessed or SetPageReferenced in shmem.c: add
those, or whatever, later on when akpm has reviewed usage elsewhere.

Patch from Hugh Dickins

Added shmem_file_sendfile to allow sendfile from tmpfs.  Checked
do_shmem_file_read and shmem_file_read against filemap equivalents
to add in any recent fixes (-EINVAL when count < 0 was missing).

Patch from Hugh Dickins

Remove obsolete shmem_fs_type: we were in some doubt whether safe yet
to do so, then found 2.5.4 typo changed it from 2.4's "shm" to "shmem"
ever since: nobody complained, delete it - we're "tmpfs" since 2.4.4.
Use libfs' simple_empty and simple_sync_file instead of homegrown.
Remove exit_shmem_fs, it fools people that this might be a module.
Allow for faint possibility that shm_mnt could not be initialized.

Patch from Hugh Dickins

Here I intended a patch to remove the unsatisfactory shmem_recalc_inode
(which tries to work out when vmscan has freed undirtied hole pages,
to relax its blocks-in-use limit; but can only do so per-inode when it
needs to be per-super).  I had hoped to use the releasepage method, but
it looks like it can't quite be bent to this task, the page might still
be rebusied after release.  2.4-ac uses a removepage method dedicated to
this, but I'm reluctant to ask for such a minor address_space_operation.

So, leave shmem_recalc_inode as is, but avoid the issue as much as
possible, by letting shmem_getpage use the empty_zero_page instead of
allocating when a hole is read (but this cannot be done when it's being
mapped, nowadays the nopage doesn't know if page will be copied or not).
Whereupon shmem_getpage(,,,SGP_READ) can do partial trunc's holdpage.

Patch from Hugh Dickins

The last set of tmpfs patches left shmem_getpage with an inadequate
next_index test to guard against races with truncation.  Now remove
that check and settle the issue with checks against i_size within
shmem_swp_alloc, which needs to know whether reading or writing.

Patch from Hugh Dickins

shmem_getpage does need to lock its page (to secure it against
shmem_writepage), but it's easier for its callers if it unlocks
before returning.  The only caller who appeared to be using the
page lock was shmem_file_write, but it wasn't actually protecting
against anything - i_sem prevents concurrent writes and truncates,
and do_shmem_file_read was dropping the lock before copying anyway.

 - name_to_kdev_t() turned into name_to_dev_t(), callers updated.
 - table of names is gone, we use driverfs instead.

 - root name is converted to dev_t only at prepare_namespace() time - we
   use to do it in setup and we need it after driver initialization.  So
   setup only stores the root name and leaves the work to
   prepare_namespace().

 - disk names for rd and cm206 changed to match the old behaviour of
   root= parser: ramdisks have ram<n> in ->disk_name now (instead of
   rd<n>) and cm206 - cm206cd (instead of cm206).

This uses better constraints that do not go through the register
unneccessarily.

Do not oops when no swapfile is available and make it compile on
DISCONTIGMEM machines.

This patch does a few cleanups/fixes with __verify_write:
 - Only compile it when needed.
 - Move test for KERNEL_DS out of line.
 - The mmap semaphore is needed to access the vma list.
 - Use fixmap for the WP test.
 - Removes an obsolete comment in fixmap.h

It was copied from i386 and is unused.

This fixes PTRACE_GETFPREGS to initilize the fpu struct correctly on
cpus with fxsr, as well as removing redundant code.

 - fixes an idiocy with floppy_find() et.al. - they forgot to set
   *part to 0.  As the result, open() on anything other than fd0 had
   lead to interesting effects...

 - fixes off-by-1 in set_disk_ro().

implementation. The optimized versions only work
for large areas, make sure we don't use them for
anything else.

configuration system, and instead just cleanly show
the dependency.

The ifdef <actual cpu selection> is very bad style, we usually introduce
feature CONFIG_ options in config.in instead.

 - cleanup
 - remove unneeded mark_inode_dirty() in fat_extend_dir()

This removes fat_cvf stuff, and adds printk() level. As far as I
know, all the challengers gave up porting of fat_cvf.
(This patch from Christoph Hellwig)

This removes the conv option. This option does nothing, now.
