     Subject: ref_tracker: remove redundant __GFP_NOWARN
has been removed from the -mm tree.  Its filename was
     ref_tracker-remove-redundant-__gfp_nowarn.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: ref_tracker: remove redundant __GFP_NOWARN
Date: Tue, 5 Aug 2025 10:30:31 +0800

Commit 16f5dfbc851b ("gfp: include __GFP_NOWARN in GFP_NOWAIT") made
GFP_NOWAIT implicitly include __GFP_NOWARN.

Therefore, explicit __GFP_NOWARN combined with GFP_NOWAIT (e.g.,
`GFP_NOWAIT | __GFP_NOWARN`) is now redundant.  Let's clean up these
redundant flags across subsystems.

No functional changes.
