Subject: [ANNOUNCE] 5.10.204-rt100
Date: Fri, 22 Dec 2023 17:41:07 -0300 [thread overview]
Message-ID: <ZYX0Y_lbe8hNUNnj@uudg.org> (raw)
Hello RT-list!
I'm pleased to announce the 5.10.204-rt100 stable release.
This release is an RT-only update.
The only change in this release is specific to RT:
rt: mm/page_alloc: backport missing bits from __build_all_zonelists() fix
A while ago upstream landed commit a2ebb51575828 ("mm/page_alloc: use
write_seqlock_irqsave() instead write_seqlock() + local_irq_save().")
to fix a problem that had already been worked on v5.10-rt via commit
7bdd3bd5143a4 ("Revert "mm/page_alloc: fix potential deadlock on
zonelist_update_seqseqlock""). Sebastian pointed out it was important
to backport the missing elements of a2ebb51575828 for code consistency.
You can get this release via the git tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git
branch: v5.10-rt
Head SHA1: 3f1186be09688c4aedf2d61176990651cf996c75
