[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled

has been removed from the -mm tree.  Its filename was
     panic-only-warn-about-deprecated-panic_print-on-write-access.patch

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

Subject: panic: only warn about deprecated panic_print on write access
Date: Tue, 6 Jan 2026 18:33:21 +0200

The panic_print_deprecated() warning is being triggered on both read and
write operations to the panic_print parameter.

This causes spurious warnings when users run 'sysctl -a' to list all
sysctl values, since that command reads /proc/sys/kernel/panic_print and
triggers the deprecation notice.

Modify the handlers to only emit the deprecation warning when the
parameter is actually being set:

 - sysctl_panic_print_handler(): check 'write' flag before warning.
 - panic_print_get(): remove the deprecation call entirely.

This way, users are only warned when they actively try to use the
deprecated parameter, not when passively querying system state.
