[Andrew Morton]

The quilt patch titled
     Subject: zram: rename ZCOMP_PARAM_NO_LEVEL
has been removed from the -mm tree.  Its filename was

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: rename ZCOMP_PARAM_NO_LEVEL
Date: Wed, 14 May 2025 11:47:50 +0900

Patch series "zram: support algorithm-specific parameters".

This patchset adds support for algorithm-specific parameters.  For now,
only deflate-specific winbits can be configured, which fixes deflate
support on some s390 setups.


This patch (of 2):

Use more generic name because this will be default "un-set"
value for more params in the future.
