Subject: [PATCH] 2.5.29 IDE 108
Date: Mon, 29 Jul 2002 21:27:12 +0200 [thread overview]
Message-ID: <3D459710.3020405@evision.ag> (raw)
In-Reply-To: Pine.LNX.4.33.0207262004550.1357-100000@penguin.transmeta.com
[-- Attachment #1: Type: text/plain, Size: 888 bytes --]
- typedef unsigned char byte; is finally gone. Everything using it should
be just ported to u8 if I missed some place where it still gets used.
- Next round of parameter parsing cleanups by Gerald Champagne.
Adjusted a bit to harmonize with hd.c.
- Move IDE register bitfields declarations over from hdparm.h to
ide.h.
- Fixup cmd640 fix by LT.
- Don't manipulate REQ_QUEUED in blk_insert_special() as discussed on
lkml. The single only affected file is ll_rw_blk.c of course.
- Declare constants needed by hd.c directly there. Those are standard
values not subject to change and we prefer a bit of code duplication
in favour of making the two drivers independant from each other.
- Move everything not ioctl related away from hdreg.h to ide.h.
This header is in effect not private to the ATA code and should
therefore not contain stuff only usefull there.
