| Matthew Wilcox | [PATCH] hash: Add explicit u32 and u64 versions of hash
The 32-bit version is more efficient (and apparently gives better hash
results than the 64-bit version), so users who are only hashing a 32-bit
quantity can now opt to use the 32-bit version explicitly, rather than
promoting to a long.

Hi,

array access if there are drives on the secondary interface

* more host drivers are switched to always tune PIO: alim15x3, cs5520,

kswapd also reclaims pagecache, not just anonymous memory. It runs

We seem to see a lot of bug reports along the lines of, "my machine

flashlight", etc. These sorts of problems are due to the fact that
the X server isn't designed to do full state save/restore, and none
of the available kernel drivers do it on its behalf.
Since intelfb and the rest of the Intel drivers are fairly incompatible,
this patch makes the DRM bind to the PCI device so it can register real

Rather than complicate matters with a second tree, use FUSE with an

compile hello.c from ~/hello.zip:

Given the desktop/embedded distinction you made, do you need both scenarios
active at the same time? If not, it seems something like a
echo -n <level> >/proc/sys/vm/danger
could do with just one sigdanger notification point? (with <level> suitably
defined as or in terms of the used threshold value).

They don't -- that's why I asked if you need both scenario's active at the

deciding through setting the level at which point applications get it.
Or put differently; what's the additional value of notifying an application
that the system is about to go balistic when you've already asked it to free
all it could earlier? SIGSEEDAMNITITOLDYOUSO?

The first threshold - "we are about to swap" - means the application
frees memory that it can. Eg. free()d memory that glibc has not yet
given back to the kernel, or JVM running the garbage collector, or ...
The second threshold - "we are out of memory" - means that the first
approach has failed and the system needs to do something else. On an
embedded system, I would expect some application to exit or maybe

That first threshold sounds fine yes. To me, the second mostly sounds like a
job for SIGTERM though.
The OOM killer could after it selected the task for killing first try a TERM
on it to give a chance to exit gracefully and only when that doesn't help
make it eligible for killing on a second round through the badness calculation.
You could moreover _never_ make a task eligible for killing before it

Well, no, that "guarantee" is fairly badly formulated but I mean "before
everyone got a SIGTERM" ofcourse. That is, first do the same selection as
now but don't send KILL but TERM and mark the task as having received a TERM
already and make it not eligible anymore. Only when there are no TERM
