This patch adds documentation to describe how to use the skid

per event as follows: pmu_instance/...,skid-ip=1/
For instance on Intel X86:

These three patches address two issues: d_weak_revalidate and
path_mountpoint lookups.
The former is poorly defined and doesn't actually do the one thing
that it would be useful for it to do. So the nfs implemention
is improved, the 9p one discarded, and the documentation clarified.
Given this c
d_weak_invalidate() is called when a path lookup ends with
something other than a simple name.
This happen when it:
- ends "." or "..",
- ends at a mountpoint (including "/"), or
- ends at a procfs symlink.
In these cases, revalidating the name of the dentry is inappropriate
as the name wasn
kern_path_mountpoint() is only called from autofs4 to perform
lookups which need to identify autofs4 mount points.
Many of the differences between kern_path() and kern_path_mountpoint()
are related to the fact that we will never use O_CREAT with the
latter, and don't need to "open" the target.
The
Now that d_weak_revalidate doesn't revalidate the inode (unless
LOOKUP_OPEN is set), we don't need any extra care when umounting.
A simple user_path_at() will find the desired dentry without
performing any access on the mounted filesystems.
So we don't need user_path_mountpoint_at().

The command "make -j8 C=1 CHECK=scripts/coccicheck" produces lots of

I do not know the coccinelle internals, but I guess --jobs does not

KBUILD_DEFCONFIG := sparc64_defconfig
The goal of these two patches is to ass endianness and machine
size info to sparse so that sparse can emit correct diagnostics
even when the endianness or machine size doesn't correspond to
sparse's defaults.
Change since v1:
- move sparse options common to sparc32 & sparc64 at the
same place.
sparc is big-endian only but sparse assumes the same endianness
as the building machine.
This is problematic for code which expect __BYTE_ORDER__ being
correctly predefined by the compiler which sparse can then
pre-process differently from what gcc would, depending on the
building machine endiannes

This change suppresses the 'dd' output and adds '-quite' parameter
to mkisofs tool. Also it removes 'Using ...' messages. None of the
messages matter to the user.
If user wants to be more verbose, he/she can use "make V=1" to debug
this script.
Now:
$ make isoimage

The NVMe device in question drops off the PCIe bus after system suspend.
I've tried several approaches to workaround this issue, but none of them
works:
- NVME_QUIRK_DELAY_BEFORE_CHK_RDY
- NVME_QUIRK_NO_DEEPEST_PS
- Disable APST before controller shutdown
- Delay between controller shutdown and sys

With this newly introduced TRACE_EVENT, it will be very easy to minotor
TCP/IPv4 state transition.
A new TRACE_SYSTEM named tcp is added, in which we can trace other TCP
event as well.
Two helpers are added,

By default, sparse assumes a 64bit machine when compiled on x86-64
and 32bit when compiled on anything else.
This can of course create all sort of problems when this doesn't
correspond to the target's machine size, like issuing false
warnings like: 'constant ... is so big it is unsigned long long'
RISC-V is little-endian only but sparse assumes the same
endianness as the building machine.

Write hints helps F2FS to determine which type of segments would be
selected for buffered write.
This patch implements the mapping from write hints to segment types

Using write hints[1], applications can inform the life time of the data

This hints help F2FS to determine the followings.

debug_arrays is not called. Also, %seen hash is not used. We should
remove unused code.
