9d1bc60138 [patch 2/7] vfs: mountinfo: add seq_file_root()
Add a new function:

  seq_file_root()

This is similar to seq_path(), but calculates the path relative to the
given root, instead of current->fs->root.  If the path was unreachable
from root, then modify the root parameter to reflect this.

6092d04818 [patch 1/7] vfs: mountinfo: add dentry_path()
[mszeredi@suse.cz] split big patch into managable chunks

Add the following functions:

  dentry_path()
  seq_dentry()

These are similar to d_path() and seq_path().  But instead of
calculating the path within a mount namespace, they calculate the path
from the root of the filesystem to a given dentry, ignoring mounts
completely.

2b47c3611d Fix f_version type: should be u64 instead of unsigned long
Fix f_version type: should be u64 instead of long

There is a type inconsistency between struct inode i_version and struct file
f_version.

fs.h:

struct inode
  u64                     i_version;

and

struct file
  unsigned long           f_version;

Users do:

fs/ext3/dir.c:

if (filp->f_version != inode->i_version) {

So why isn't f_version a u64 ? It becomes a problem if versions gets
higher than 2^32 and we are on an architecture where longs are 32 bits.

This patch changes the f_version type to u64, and updates the users accordingly.

It applies to 2.6.23-rc2-mm2.

call seq_open(). The __seq_open_private() helper returns

bcf67e1625 Make common helpers for seq_files that work with list_heads
Many places in kernel use seq_file API to iterate over a regular list_head.
The code for such iteration is identical in all the places, so it's worth
introducing a common helpers.

This makes code about 300 lines smaller:

The first version of this patch made the helper functions static inline
in the seq_file.h header. This patch moves them to the fs/seq_file.c as
Andrew proposed. The vmlinux .text section sizes are as follows:

2.6.22-rc1-mm1:              0x001794d5
with the previous version:   0x00179505
with this patch:             0x00179135

The config file used was make allnoconfig with the "y" inclusion of all
the possible options to make the files modified by the patch compile plus
drivers I have on the test node.

This patch:

15ad7cdcfd [PATCH] struct seq_operations and struct file_operations constification
- move some file_operations structs into the .rodata section

 - move static strings from policy_types[] array into the .rodata section

 - fix generic seq_operations usages, so that those structs may be defined
   as "const" as well

1da177e4c3 Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
