Okay, I'm in the middle of developing a pseudo device driver under
2.2.18. Processes that use it generally mmap() it, and in the mmap
handler, it sets up a nopage handler. Here's the question: After the
nopage handler has been called and pages have been mapped to client
processes' spaces, ho

Hey all. I recently noticed, while setting up a disk image for plex86, a
bug in loopback mounting. This happens on at least 2.4.0 and 2.4.0-ac9.
Steps for me to reproduce (as root):
1) losetup /dev/loop0 losetup -o $((512*63)) /dev/loop0 /usr/src/emu/plex86/guest/hdd
2) mount /dev/loop0 /mnt
3)
Pentium-III 256Mb BE6.
1) top (procps-2.0.7) gives me the messages :
'bad data in /proc/uptime'
'bad data in /proc/loadavg'
cat /proc/uptime
1435.30 904.74
cat /proc/loadavg
0.01 0.21 0.29 1/17 19444
What is wrong ?
2) pppd (2.4.0b4) gives me the message :
'tdb_store failed : Success'

I've written a brief article on the topic of using test suites to test new linux

It is my hope that anyone who wants to play with the new kernels will try out

in this case there could still be valid performance differences, as
copying from user-space is cheaper than copying from the pagecache. To
rule out SMP interactions, you could try a UP-IOAPIC kernel on that
Hi,
I tried a little further, 2.2.19p2 still works, 2.2.19p3 not.

I *did* rebuilt my iBCS each time after building (and rebooting) a

In that case just a user space buffer is sent i.e no file association.

I should also add that the 3.11 driver seems to make things better, but
not yet perfect. My intuition tells me that I get CRC errors much sooner
with 2.1e than with 3.11.
Has the timings changed from 2.1e to 3.11, and would it be easy to modify
3.11 to get extra safe/paranoid, but less high perf

Hi.
The following patch makes drivers/scsi/atari_scsi.c check request_irq's
return code. It applies cleanly against 240p3 and ac9.

Hi.
(I cannot seem to find a maintainer for this code.)
The following patch makes drivers/scsi/a3000.c check the return from
request_irq. Applies cleanly against 2.4.0 and ac9.

You need modutils >= 2.4.0

I thought i'd run some tests on the new zerocopy patches
(this is using a hacked ttcp which knows how to do sendfile
and does MSG_TRUNC for true zero-copy receive, if you know what i mean

Hi Linus,
While playing with the shmem read/write support I realised that the
accounting for shmem is broken:
Since we do not mark the page dirty at allocation time the vm can drop
it at any time as long as it is not written to. But shmem never
adjusts its accounting to that and will happily inc

SCSI device errors that only occur in a SMP machine with an aic7xxx with
