[merged mm-stable] zram-drop-unused-bio-parameter-from-write-helpers.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: zram: drop unused bio parameter from write helpers
has been removed from the -mm tree.  Its filename was
     zram-drop-unused-bio-parameter-from-write-helpers.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: zram: drop unused bio parameter from write helpers
Date: Thu, 28 May 2026 10:48:45 +0800

After "zram: fix use-after-free in zram_bvec_write_partial()",
zram_bvec_write_partial() always passes NULL to zram_read_page() and no
longer needs the parent bio.  Mirror the read side
(zram_bvec_read_partial() has not taken a bio since commit 4e3c87b9421d
("zram: fix synchronous reads")) and drop the parameter from
zram_bvec_write_partial() and zram_bvec_write().

No functional change.
