Subject: [ANNOUNCE] v5.10-rc3-rt6

Dear RT folks!

I'm pleased to announce the v5.10-rc3-rt6 patch set. 

Changes since v5.10-rc3-rt5:

  - The new migrate-disable didn't release a lock in an error path.
    Reported by Joe Korty.

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.

The delta patch against v5.10-rc3-rt5 is appended below and can be found here:
 
     https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/incr/patch-5.10-rc3-rt5-rt6.patch.xz

You can get this release via the git tree at:

    git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git v5.10-rc3-rt6

The RT patch against v5.10-rc3 can be found here:

    https://cdn.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patch-5.10-rc3-rt6.patch.xz
