According to the xhci specification(chapter 4.6.8.1) soft retry
shouldn't be used if the slot id is higher than 0. Currently some usb
devices break on some systems because soft retry is being used when
there is a transaction error, without checking the slot id.

The tests use both shared and private mapped hugetlb memory, and

counter. They test different configurations such as hugetlb memory usage
via hugetlbfs, or MAP_HUGETLB, or shmget/shmat, and with and without
MAP_POPULATE.
For shared mappings, the pointer to the hugetlb_cgroup to uncharge lives
in the resv_map entries, in file_region->reservation_counter.
After a call to region_chg, we charge the approprate hugetlb_cgroup, and if
successful, we pass on the hugetlb_cgroup info to a follow up region_add call.

Support MAP_NORESERVE accounting as part of the new counter.
For each hugepage allocation, at allocation time we check if there is
a reservation for this allocation or not. If there is a reservation for
this allocation, then this allocation was charged at reservation time,
and we don't re-account
Normally the pointer to the cgroup to uncharge hangs off the struct
page, and gets queried when it's time to free the page. With
hugetlb_cgroup reservations, this is not possible. Because it's possible
for a page to be reserved by one task and actually faulted in by another
task.

From: Himadri Pandya
Current code assumes PAGE_SIZE (the guest page size) is equal
to the page size used to communicate with Hyper-V (which is
always 4K). While this assumption is true on x86, it may not
be true for Hyper-V on other architectures. For example,
Linux on ARM64 may have PAGE_SIZE
Augments hugetlb_cgroup_charge_cgroup to be able to charge hugetlb
usage or hugetlb reservation counter.
Adds a new interface to uncharge a hugetlb_cgroup counter via
hugetlb_cgroup_uncharge_counter.
Integrates the counter with hugetlb_cgroup, via hugetlb_cgroup_init,
hugetlb_cgroup_have_usage,
These counters will track hugetlb reservations rather than hugetlb
memory faulted in. This patch only adds the counter, following patches
add the charging and uncharging of the counter.

This patchset adds a IIO driver for the Bosch BMA400 3-axes ultra low-power
accelerometer. The initial implementation of the driver adds read support for
the acceleration and temperature data registers. The driver also has support
for reading and writing to the output data rate, oversampling

Dear Friend
Please accept my apologies if this request does not meet your personal ethics
as it is not intended to cause you any embarrassment in what ever form. I got

The idea is to support multiple ring formats by converting
to a format-independent array of descriptors.
This costs extra cycles, but we gain in ability
to fetch a batch of descriptors in one go, which
is good for code cache locality.
To simplify benchmarking, I kept the old code
around so one
With this patch applied, new and old code perform identically.
Lots of extra optimizations are now possible, e.g.
we can fetch multiple heads with copy_from/to_user now.
We can get rid of maintaining the log array. Etc etc.

This adds infrastructure required for supporting
multiple ring formats.
The idea is as follows: we convert descriptors to an
independent format first, and process that converting to
iov later.
The point is that we have a tight loop that fetches
descriptors, which is good for cache utilization.
Add a new sysctl knob unprivileged_userfaultfd_user_mode_only.
This sysctl can be set to either zero or one. When zero (the default)
the system lets all users call userfaultfd with or without
UFFD_USER_MODE_ONLY, modulo other access controls. When
unprivileged_userfaultfd_user_mode_only is set to

This change adds 2 as an allowable value for
unprivileged_userfaultfd. (Previously, this sysctl could be either 0
or 1.) When unprivileged_userfaultfd is 2, users with CAP_SYS_PTRACE
may create userfaultfd with or without UFFD_SECURE, but users without
CAP_SYS_PTRACE must pass UFFD_SECURE to
Use the secure anonymous inode LSM hook we just added to let SELinux
policy place restrictions on userfaultfd use. The create operation
applies to processes creating new instances of these file objects;
transfer between processes is covered by restrictions on read, write,

A secure anonymous file is one we hooked up to its own inode (as
opposed to the shared inode we use for non-secure anonymous files). A
new selinux hook gives security modules a chance to initialize, label,
and veto the creation of these secure anonymous files. Security
modules had limit ability to
Add functions forwarding from the old names to the new ones so we

The new secure flag makes userfaultfd use a new "secure" anonymous
file object instead of the default one, letting security modules
supervise userfaultfd use.
Requiring that users pass a new flag lets us avoid changing the
semantics for existing callers.

Userfaultfd in unprivileged contexts could be potentially very
useful. We'd like to harden userfaultfd to make such unprivileged use
less risky. This patch series allows SELinux to manage userfaultfd
file descriptors (via a new flag, for compatibility with existing
code) and allows administrators
userfaultfd handles page faults from both user and kernel code. Add a
new UFFD_USER_MODE_ONLY flag for userfaultfd(2) that makes the
resulting userfaultfd object refuse to handle faults from kernel mode,
treating these faults as if SIGBUS were always raised, causing the
kernel code to fail with

Hello,
I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “ieee80211_send_assoc” contains still an unchecked call
of the function “kmemdup”.
