[merged] hung_task-decrement-sysctl_hung_task_warnings-only-if-it-is-positive.patch removed from -mm tree

[akpm]

The patch titled
     Subject: hung_task: decrement sysctl_hung_task_warnings only if it is positive
has been removed from the -mm tree.  Its filename was
     hung_task-decrement-sysctl_hung_task_warnings-only-if-it-is-positive.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp>
Subject: hung_task: decrement sysctl_hung_task_warnings only if it is positive

Since sysctl_hung_task_warnings == -1 is allowed (infinite warnings),
48a6d64edadbd40f ("hung_task: allow hung_task_panic when
hung_task_warnings is 0") should decrement it only when it is not -1.

This prevents the kernel from ceasing warnings after the first 4294967295 ;)
