Ingo Molnar 923f4f2394 [PATCH] pipe.c/fifo.c code cleanups
more code cleanups after the macro conversion:

 - standardize on 'struct pipe_inode_info *pipe' variable names
 - introduce 'pipe' temporaries to reduce mass inode->i_pipe dereferencing

Ingo Molnar 3a326a2ce8 [PATCH] introduce a "kernel-internal pipe object" abstraction
separate out the 'internal pipe object' abstraction, and make it
usable to splice. This cleans up and fixes several aspects of the
internal splice APIs and the pipe code:

 - pipes: the allocation and freeing of pipe_inode_info is now more symmetric
   and more streamlined with existing kernel practices.

 - splice: small micro-optimization: less pointer dereferencing in splice
   methods

Arjan van de Ven 4b6f5d20b0 [PATCH] Make most file operations structs in fs/ const
This is a conversion to make the various file_operations structs in fs/
const.  Basically a regexp job, with a few manual fixups

The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)

Linus Torvalds d19e997408 Simplify fifo_open() locking logic
We don't do interruptible waits for the pipe mutex anywhere else any
more either, so don't do it in fifo_open() either.

Jes Sorensen 1b1dcc1b57 [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem
This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.

(finished the conversion)

Linus Torvalds 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!
