Subject: [ANNOUNCE] v5.9-rc2-rt1

Dear RT folks!

I'm pleased to announce the v5.9-rc2-rt1 patch set. 

Changes since v5.6.19-rt12:

  - Rebase to v5.9-rc2

  - The seqcount related patches have been replaced on top of the
    seqcount series by Ahmed S. Darwis which landed mainline. 

  - The posix-timer patches have been dropped because upstream changes
    cover all of was needed on RT's side. As a result RT relies on
    HAVE_POSIX_CPU_TIMERS_TASK_WORK. This is provided only by x86.
    The RT patch provides this option for ARM/ARM64/POWERPC as long as
    KVM is disabled. The reason is that the task work must be handled
    before KVM returns to guest.

Known issues
     - It has been pointed out that due to changes to the printk code the
       internal buffer representation changed. This is only an issue if tools
       like `crash' are used to extract the printk buffer from a kernel memory
       image.

You can get this release via the git tree at:

    git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.9-rc2-rt1
