When tracing in X we get event loops due to the tracing activity, i.e.
updates to a gnome-terminal that generate syscalls for X.org, etc.
To get a more useful view of what is happening, syscall wise, system
wide, we need to filter those, like in:

add some belt'n'braces code to ensure that cnt != 0, otherwise

Hi,
CONFIG_DEBUG_SET_MODULE_RONX is currently non-functional on arm and arm64
because of changes in behavior of is_module_addr. This series fixes
both arm and arm64 to work correctly and corrects a minor bug
related to section alignment in modules.
Laura Abbott (3):
arm64: Don't use is_module_a
When CONFIG_DEBUG_SET_MODULE_RONX is enabled, the sizes of
module sections are aligned up so appropriate permissions can
be applied. Adjusting for the symbol table may cause them to
become unaligned. Make sure to re-align the sizes afterward.

need to switch the mux off the M/N counter to an always on source

Adds the set-2038 test which sets the time to near-edge cases
like the start and end of the 32 bit epoch and checks that

lets the clock roll over past 2038 on 32bit systems, which

At the context we have pointer to struct phy, it's useful to call
phy_get_drvdata() to get the address of cluster_phy. This has slightly
better readability than calling dev_get_drvdata(phy->dev.parent).

Hello,
here is an updated richacl patch queue, also available in git [1]. For those
who might not know, richacls are an implementation of NFSv4 ACLs that cleanly
integrates into the POSIX file permission model. The goal is to improve
interoperability between Linux and other systems, mainly acros

Any comments on this?
I'm going to propose a patch to the mmc framework calling this api, so
it would be good to know
Richacls distinguish between creating non-directories and directories. To
support that, add an isdir parameter to may_create(). When checking
inode_permission() for create permission, pass in an additional MAY_CREATE_FILE
or MAY_CREATE_DIR mask flag.

POSIX ACLs and richacls are both objects allocated by kmalloc() with a
reference count which are freed by kfree_rcu(). An inode can either cache an
access and a default POSIX ACL, or a richacl. (Richacls do not have default
acls). To allow an inode to cache either of the two kinds of acls, intro

Support the richacl permission model in ext4. The richacls are stored in
"system.richacl" xattrs. Richacls need to be enabled by tune2fs or at file
system create time.

This feature flag selects richacl instead of posix acl support on the file
system. In addition, the "acl" mount option is needed for enabling either of
the two kinds of acls.

Automatic Inheritance (AI) allows changes to the acl of a directory to
recursively propagate down to files and directories in the directory.
To implement this, the kernel keeps track of which permissions have been
inherited, and makes sure that permission propagation is turned off when the
file pe
When a new file is created, it can inherit an acl from its parent
directory; this is similar to how default acls work in POSIX (draft)
ACLs.
As with POSIX ACLs, if a file inherits an acl from its parent directory,
the intersection between the create mode and the permissions granted by
the inherite
This function is used to avoid storing richacls if the acl can be computed from
the file permission bits.

Doing a chmod() sets the file mode, which includes the file permission
bits. When a file has a richacl, the permissions that the richacl
grants need to be limited to what the new file permission bits allow.
This is done by setting the file masks in the richacl to what the file
permission bits map
A richacl consists of an NFSv4 acl and an owner, group, and other mask.
These three masks correspond to the owner, group, and other file
permission bits, but they contain NFSv4 permissions instead of POSIX
permissions.
Each entry in the NFSv4 acl applies to the file owner (OWNER@), the owning
grou
Compute upper bound owner, group, and other file masks with as few
permissions as possible without denying any permissions that the NFSv4
acl in a richacl grants.
This algorithm is used when a file inherits an acl at create time and
when an acl is set via a mechanism that does not specify file mod
A richacl grants a requested access if the NFSv4 acl in the richacl grants the
requested permissions (according to the NFSv4 permission check algorithm) and
the file mask that applies to the process includes the requested permissions.
