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: https://www.kernel.org/pub/linux/kernel/v5.x/linux-5.10.tar.xz https://www.kernel.org/pub/linux/kernel/v5.x/patch-5.10.180.xz https://www.kernel.org/pub/linux/kernel/projects/rt/5.10/older/patch-5.10.180-rt88.patch.xz Signing key fingerprint: 9354 0649 9972 8D31 D464 D140 F394 A423 F8E6 7C26 All keys used for the above files and repositories can be found on the following git repository: git://git.kernel.org/pub/scm/docs/kernel/pgpkeys.git Enjoy!
