Move BKL into ->put_super from the only caller. A couple of
filesystems had trivial enough ->put_super (only kfree and NULLing of
s_fs_info + stuff in there) to not get any locking: coda, cramfs, efs,
hugetlbfs, omfs, qnx4, shmem, all others got the full treatment. Most
of them probably don't need it, but I'd rather sort that out individually.
Preferably after all the other BKL pushdowns in that area.[AV: original used to move lock_super() down as well; these changes are
removed since we don't do lock_super() at all in generic_shutdown_super()
now]
[AV: fuse, btrfs and xfs are known to need no damn BKL, exempt]Signed-off-by: Christoph Hellwig

This is a much better version of a previous patch to make the parser
tables constant. Rather than changing the typedef, we put the "const" in
all the various places where its required, allowing the __initconst
exception for nfsroot which was the cause of the previous trouble.This was posted for review some time ago and I believe its been in -mm
since then.Signed-off-by: Steven Whitehouse

Some iso9660 images contain files with rockridge data that is either
incorrect or incompletely parsed. Prior to commit
f2966632a134e865db3c819346a1dc7d96e05309 ("[PATCH] rock: handle directory
overflows") (included with kernel 2.6.13) the kernel ignored the rockridge
data for these files, while still allowing the files to be accessed under
their non-rockridge names. That commit inadvertently changed things so
that files with invalid rockridge data could not be accessed at all. (I
ran across the problem when comparing some old CDs with hard disk copies I
had made long ago under kernel 2.4: a few of the files on the hard disk
copies were no longer visible on the CDs.)This change reverts to the pre-2.6.13 behavior.

When a directory on isofs is corrupted, we did not check whether length of the
name in a directory entry and the length of the directory entry itself are
consistent. This could lead to possible access beyond the end of buffer when
the length of the name was too big. Add this sanity check to directory

A read request outside i_size will be handled in do_generic_file_read(). So
we just return 0 to avoid getting -EIO as normal reading, let
do_generic_file_read do the rest.At the same time we need unlock the page to avoid system stuck.

It turned out that mounting a corrupted ISO image to a regular file may
succeed, e.g. if an image was prepared as follows:$ dd if=correct.iso of=bad.iso bs=4k count=8
We then can mount it to a regular file:
# mount -o loop -t iso9660 bad.iso /tmp/file
But mounting it to a directory fails with -ENOTDIR, simply because
the root directory inode doesn't have S_IFDIR set and the condition
in graft_tree() is met:if (S_ISDIR(nd->dentry->d_inode->i_mode) !=
S_ISDIR(mnt->mnt_root->d_inode->i_mode))
return -ENOTDIRThis is because the root directory inode was read from an incorrect
block. It's supposed to be read from sbi->s_firstdatazone, which is
an absolute value and gets messed up in the case of an incorrect image.In order to somehow circumvent this we have to check that the root
directory inode is actually a directory after all.Signed-off-by: Kirill Kuvaldin

I have never seen a use of SLAB_DEBUG_INITIAL. It is only supported by
SLAB.I think its purpose was to have a callback after an object has been freed
to verify that the state is the constructor state again? The callback is
performed before each freeing of an object.I would think that it is much easier to check the object state manually
before the free. That also places the check near the code object
manipulation of the object.Also the SLAB_DEBUG_INITIAL callback is only performed if the kernel was
compiled with SLAB debugging on. If there would be code in a constructor
handling SLAB_DEBUG_INITIAL then it would have to be conditional on
SLAB_DEBUG otherwise it would just be dead code. But there is no such code
in the kernel. I think SLUB_DEBUG_INITIAL is too problematic to make real
use of, difficult to understand and there are easier ways to accomplish the
same effect (i.e. add debug code before kfree).There is a related flag SLAB_CTOR_VERIFY that is frequently checked to be
clear in fs inode caches. Remove the pointless checks (they would even be
pointless without removeal of SLAB_DEBUG_INITIAL) from the fs constructors.This is the last slab flag that SLUB did not support. Remove the check for
unimplemented flags from SLUB.Signed-off-by: Christoph Lameter

There was an I/O error that prevented reading the last partial block of
large files in an ISO9660 filesystem. The error was generated when a file
comprised more than one section and had a size that was not an exact
multiple of the filesystem block size. This patch removes the check (and
failure) for reading into the last partial block (and possibly beyond) for
multiple-section files.It worked in my testing to prevent reading beyond the end of the section;
my first patch just incremented the sect_size block count for a partial
block and continued doing the check. But there is a commment in the source
code about reading beyond the end of the file to fill a page cache.
Failing to access beyond the section would prevent reading beyond the end
of the file.Signed-off-by: Andrew Morton

This eliminates the i_blksize field from struct inode. Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.[bunk@stusta.de: cleanup]
