Dear RT Folks, I'm pleased to announce the 5.4.91-rt50 stable release. This release is just an update to the new stable 5.4.91 version. With one RT specific update that had to be made. I had to cherry pick the following commit: locking/rwsem-rt: Add __down_read_interruptible() from v5.10-rt, as that was required for a recent change in 5.4.88. d390fc97df62d ("rwsem: Implement down_read_interruptible") 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: v5.4-rt Head SHA1: 11ad0451731e7ab8c57281843015717e0e8040ef Or to build 5.4.91-rt50 directly, the following patches should be applied: http://www.kernel.org/pub/linux/kernel/v5.x/linux-5.4.tar.xz http://www.kernel.org/pub/linux/kernel/v5.x/patch-5.4.91.xz http://www.kernel.org/pub/linux/kernel/projects/rt/5.4/patch-5.4.91-rt50.patch.xz Enjoy, -- Steve
