Perf top raise a warning if a kernel sample is collected but kernel map

However, previous perf_event__preprocess_sample() doesn't always

mangle_path accepts a string listing the characters it's supposed to

we be escaping '\' regardless, since it's the character used to signal

The patch adds a debug driver, which dumps the power states

Christoph,
We had internal discussion with our engineering and management on this
topic. We are committed to provide bug fixes ( Only bug fixes and no new
features) across both the SAS2 and SAS3 source trees. We prefer the SAS2
and SAS3 drivers to stay separate and the reason is; merging of the

Right, that's why the two patches kinda got lost. Rik, sorry about
that and yes these two should go through Peterz.
Thanks.

Before back porting this to ACPICA, let me ask one simple question.
According to the spec, the _CLS is optional and PCI specific.
So why should we implement it in ACPICA core not OSPM specific modules?

It's been five years now that KM_* kmap flags have been removed and

Hi,
I'm trying revive an old debate here[1], though with a simpler approach than
was previously tried. This patch series implements a new option to sanitize
freed pages, a (very) small subset of what is done in PaX/grsecurity[3],
inspired by a previous submission [4].
The first patch is fairly in
