The quilt patch titled
Subject: lib/alloc_tag: use %pe format specifier
has been removed from the -mm tree. Its filename was
alloc_tag-use-%pe-format-specifier.patch
This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: lib/alloc_tag: use %pe format specifier
Date: Wed, 5 Nov 2025 10:39:25 +0800
The %pe format specifier is designed to print error pointers. It prints a
symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR();
This patch fixes this cocci report:
lib/alloc_tag.c:776:63-70: WARNING: Consider using %pe to print PTR_ERR()
