Daniel Mack 997ea58eb9 USB: rename usb_buffer_alloc() and usb_buffer_free() users
For more clearance what the functions actually do,

  usb_buffer_alloc() is renamed to usb_alloc_coherent()
  usb_buffer_free()  is renamed to usb_free_coherent()

They should only be used in code which really needs DMA coherency.

All call sites have been changed accordingly, except for staging
drivers.

Mariusz Kozlowski 3c8961ee6d usb: writing_usb_driver free urb cleanup
Allright. As Greg KH suggested I split this big patch into smaller ones to
make the changes easier to review. Having no better idea how to split that I 
split it on a 'patch per file' basis. All those patches clean redundant 'if' before 
usb_unlink/free/kill_urb():

if (urb)
	usb_free_urb(urb); /* unlink / free / kill */

I decided not to touch bigger 'if's like 

if (urb) {
	usb_kill_urb(urb);
	usb_free_urb(urb);
	urb = NULL;
}

as that would be probably too intrusive. One of patches also fixes 
drivers/usb/misc/auerswald.c memleak I found when digging the code. All those
patches are against 2.6.19-rc4.

Adrian Bunk bf6ee0ae49 remove mentionings of devfs in documentation
Now that devfs is removed, there's no longer any need to document how to
do this or that with devfs.

This patch includes some improvements by Joe Perches.

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!
