I'm announcing the release of the 5.4.132 kernel.
All users of the 5.4 kernel series must upgrade.
The updated 5.4.y git tree can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.4.y
and can be browsed at the normal kernel.org git web browser:
https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git;a=summary
thanks,
greg k-h

+ Echoing a value is additive, the new value is added to the

+ For example, after::

+ another echo can be performed::

+ Loading an HMAC key is the only way to disable metadata

Until key loading has been signaled EVM can not create

+ * 1) A lock_list can be either forwards or backwards for a lock dependency,

+ * a) lock_list in the ->locks_after list of A, whose ->class is B and

+ * b) lock_list in the ->locks_before list of B, whose ->class is A
+ * and ->links_to is B. In this case, we can say the lock_list is
+ * "B <- A" (bacwards case).
+ *
+ * The ->trace of both a) and b) point to the call trace where B was
+ * acquired with A held.
+ *
+ * 2) A "helper" lock_list is introduced during BFS, this lock_list doesn't
+ * represent a certain lock dependency, it only provides an initial entry
+ * for BFS. For example, BFS may introduce a "helper" lock_list whose
+ * ->class is A, as a result BFS will search all dependencies starting with
+ * A, e.g. A -> B or A -> C.
+ *
+ * The notation of a forwards helper lock_list is like "-> A", which means
+ * we should search the forwards dependencies starting with "A", e.g A -> B
+ * or A -> C.
+ *
+ * The notation of a bacwards helper lock_list is like "<- B", which means
+ * we should search the backwards dependencies ending with "B", e.g.
