Hello,
one small question... Will O_DSYNC flag be available in Linux?
It is available at least on AIX, and HP-UX. The difference with O_SYNC is the
same as between fsync and fdatasync.
Any comments?

Because it may find the thing in cache. Uptodate and unlocked. Since you

Hi,
My IBM Thinkpad 600E changes between 100MHz and 400MHz depending if the

For example, I am interested in discriminating between

1. To maximize compatibility, sys_sysinfo() tries to replace page

most likely overflow. Just try adding a few 2GB swaps to your

I am against any API which provides this. It can be extremely
expensive to do this on some architectures, and since the rest
of the PCI dma API does not provide such an interface neither
drivers/char/hfmodem/refclock.c fails to compile with "gcc version 2.95.2
2220 (Debian GNU/Linux)", but compiles normally with "gcc version
2.7.2.3". GNU assembler 2.9.5 was used in both cases. Here is the error
message:
refclock.c: In function `hfmodem_refclock_current':

Well, I stand corrected. Look forward to trying it out.

Hmm, so the Intel 815 and DMA doesn't mix with 2.2.x? What about
Andre's IDE patches?

I've got a Gateway here with a Intel 815 chipset running 2.2.18. Inside
it's a PIII 733 with 512MB and a Quantum lct15 drive.
The problem is that the IDE driver doesn't recognize the IDE
conroller, so DMA isn't enabled leading to some poor drive
performance. Here's the relevant sections from
On Tyan Thunderbird 2510 MBd with server works le bios and dual eepro100

This came out a little backassward.. pivot_root then chroot/unmount.
