[merged mm-nonmm-stable] checkstack-allow-to-pass-minstacksize-parameter.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: checkstack: allow to pass MINSTACKSIZE parameter
has been removed from the -mm tree.  Its filename was
     checkstack-allow-to-pass-minstacksize-parameter.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: checkstack: allow to pass MINSTACKSIZE parameter
Date: Mon, 20 Nov 2023 19:37:19 +0100

The checkstack script omits all functions with a stack usage of less than
100 bytes.  However the script already has support for a parameter which
allows to override the default, but it cannot be set with

$ make checkstack

Add a MINSTACKSIZE parameter which allows to change the default. This might
be useful in order to print the stack usage of all functions, or only those
with large stack usage:

$ make checkstack MINSTACKSIZE=0
$ make checkstack MINSTACKSIZE=800
