Subject: Please apply 90dfeef1cd38 to 6.1 through 6.18
Date: Fri, 24 Jul 2026 18:13:42 -0700 [thread overview]
Message-ID: <20260725011342.GA2792705@ax162> (raw)
Hi stable folks,
Upstream commit cc39f3872c08 ("seqlock: Introduce
scoped_seqlock_read()") was backported in several stable branches (6.18
through 6.1) recently without a necessary fix, commit 90dfeef1cd38
("seqlock: Cure some more scoped_seqlock() optimization fails"),
breaking the build for certain configurations
https://github.com/ClangBuiltLinux/linux/issues/2178
Please consider applying 90dfeef1cd38 to 6.18 through 6.1 to avoid this,
it applies cleanly to all those trees for me. You may also want to
consider taking
b94d45b6bbb4 ("seqlock: Allow KASAN to fail optimizing")
88331c4ec23a ("seqlock: Allow UBSAN_ALIGNMENT to fail optimizing")
but I did not test if they were clean cherry picks.

Cheers,
Nathan
