[RFC PATCH v2 0/2] hung_task: Display every hung task warning

From: atomlin

From: Aaron Tomlin <atomlin@xxxxxxxxxx>

The khungtaskd thread limits how many hung task warnings it displays
at a time, when a timeout occurs. This patch allows that limit to be
set to "unlimited", by setting hung_task_warnings to -1, which will
cause khungtaskd to display information about all hung tasks.

While ULONG_MAX is practically "inf", this patch takes it one step
further. Note: The maximum is now 2^31-1 (INT_MAX) which should
hopefully be sufficient.

Rebased against v3.13-rc8.

Aaron Tomlin (2):
sysctl: Make neg_one a standard constraint
hung_task: Display every hung task warning
