[git pull] IDE updates part 4
From: Bartlomiej Zolnierkiewicz
Date: Tue Apr 07 2009 - 18:18:38 EST
[ Sigh, seems like I'm 42 minutes late... ]
Hi,
The final bits:
- bug fixes for few fallouts from previous IDE updates (Geert Uytterhoeven)
- TRIM support ("discard" operation for SSD devices)
(David Woodhouse & Matthew Wilcox)
Since this is a new feature and hasn't seen much testing with production
devices it is not enabled by default yet (requires use of "ide_core.trim=1"
kernel parameter).
- at91_ide host driver updates including PIO6 support (Stanislaw Gruszka)
- tx493[89]ide host driver updates (Atsushi Nemoto)
- simplififcation of 'struct ide_taskfile' and tf_{read,load}() methods
(Sergei Shtylyov)
The nice end effect of this work is clearly visible in diffstat.
- ide-cd: initial unification of error handling for fs and pc requests
(Borislav Petkov)
- removal of superfluous write memory barriers (Grant Grundler)
I also included obviously correct xsysace fix (from Grant Likely, xsysace
Maintainer) for the very recent regression introduced by my <linux/hdreg.h>
cleanups (just to make life easier for everybody).
Linus, please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/
