-For zoned file systems, the following attributes are exposed in:
-
- /sys/fs/xfs/<dev>/zoned/
-
- max_open_zones                 (Min:  1  Default:  Varies  Max:  UINTMAX)
-        This read-only attribute exposes the maximum number of open zones
-        available for data placement. The value is determined at mount time and
-        is limited by the capabilities of the backing zoned device, file system
-        size and the max_open_zones mount option.

-        Define a percentage for how much of the unused space that GC should keep
-        available for writing. A high value will reclaim more of the space
-        occupied by unused blocks, creating a larger buffer against write
-        bursts at the cost of increased write amplification.  Regardless
-        of this value, garbage collection will always aim to free a minimum
-        amount of blocks to keep max_open_zones open for data placement purposes.

+Q: What "BPF_INTERNAL" symbol namespace is for?
+-----------------------------------------------
+A: Symbols exported as BPF_INTERNAL can only be used by BPF infrastructure
+like preload kernel modules with light skeleton. Most symbols outside
+of BPF_INTERNAL are not expected to be used by code outside of BPF either.
+Symbols may lack the designation because they predate the namespaces,
+or due to an oversight.

- * - %LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF: Do not create any log related to the
- *   enforced restrictions.  This should only be set by tools launching unknown
- *   or untrusted programs (e.g. a sandbox tool, container runtime, system
- *   service manager).  Because programs sandboxing themselves should fix any
- *   denied access, they should not set this flag to be aware of potential
- *   issues reported by system's logs (i.e. audit).
- * - %LANDLOCK_RESTRICT_SELF_LOG_NEW_EXEC_ON: Explicitly ask to continue
- *   logging denied access requests even after an :manpage:`execve(2)` call.
- *   This flag should only be set if all the programs than can legitimately be
- *   executed will not try to request a denied access (which could spam audit
- *   logs).
- * - %LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF: Do not create any log related
- *   to the enforced restrictions coming from future nested domains created by
- *   the caller or its descendants.  This should only be set according to a
- *   runtime configuration (i.e. not hardcoded) by programs launching other
- *   unknown or untrusted programs that may create their own Landlock domains
- *   and spam logs.  The main use case is for container runtimes to enable users
- *   to mute buggy sandboxed programs for a specific container image.  Other use
- *   cases include sandboxer tools and init systems.  Unlike
- *   %LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF,
- *   %LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF does not impact the requested
- *   restriction (if any) but only the future nested domains.
+ * **Flags**
+ *
+ * By default, denied accesses originating from programs that sandbox themselves
+ * are logged via the audit subsystem. Such events typically indicate unexpected
+ * behavior, such as bugs or exploitation attempts. However, to avoid excessive
+ * logging, access requests denied by a domain not created by the originating
+ * program are not logged by default. The rationale is that programs should know
+ * their own behavior, but not necessarily the behavior of other programs.  This
+ * default configuration is suitable for most programs that sandbox themselves.
+ * For specific use cases, the following flags allow programs to modify this
+ * default logging behavior.
+ *
+ * The %LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF and
+ * %LANDLOCK_RESTRICT_SELF_LOG_NEW_EXEC_ON flags apply to the newly created
+ * Landlock domain.
+ *
+ * %LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF
+ *     Disables logging of denied accesses originating from the thread creating
+ *     the Landlock domain, as well as its children, as long as they continue
+ *     running the same executable code (i.e., without an intervening
+ *     :manpage:`execve(2)` call). This is intended for programs that execute
+ *     unknown code without invoking :manpage:`execve(2)`, such as script
+ *     interpreters. Programs that only sandbox themselves should not set this
+ *     flag, so users can be notified of unauthorized access attempts via system
+ *     logs.
+ *
+ * %LANDLOCK_RESTRICT_SELF_LOG_NEW_EXEC_ON
+ *     Enables logging of denied accesses after an :manpage:`execve(2)` call,
+ *     providing visibility into unauthorized access attempts by newly executed
+ *     programs within the created Landlock domain. This flag is recommended
+ *     only when all potential executables in the domain are expected to comply
+ *     with the access restrictions, as excessive audit log entries could make
+ *     it more difficult to identify critical events.
+ *
+ * %LANDLOCK_RESTRICT_SELF_LOG_SUBDOMAINS_OFF
+ *     Disables logging of denied accesses originating from nested Landlock
+ *     domains created by the caller or its descendants. This flag should be set
+ *     according to runtime configuration, not hardcoded, to avoid suppressing
+ *     important security events. It is useful for container runtimes or
+ *     sandboxing tools that may launch programs which themselves create
+ *     Landlock domains and could otherwise generate excessive logs. Unlike
+ *     ``LANDLOCK_RESTRICT_SELF_LOG_SAME_EXEC_OFF``, this flag only affects
+ *     future nested domains, not the one being created. It can also be used
+ *     with a @ruleset_fd value of -1 to mute subdomain logs without creating a
+ *     domain.
