Hello RT-list!
I'm pleased to announce the 5.10.180-rt88 stable release.
This release is an update to the new stable 5.10.180 version, with one
RT-specific change required to fix a build error due to the lack of
support for deferred printing in v5.10-rt.
Support for deferred printing was removed in v5.10-rc1-rt1 by commit
9153e3c5cb0c9 ("printk: remove deferred printing").
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: 442a576e3b9afa5272c3d0a996a0d1a260f259b8
Or to build 5.10.180-rt88 directly, the following patches should be applied:
