[Ceph-announce] Luminous v12.2.3 released

We're happy to announce the third bugfix release of Luminous v12.2.x long term stable release series. It contains a range of bug fixes and stability improvements across Bluestore, CephFS, RBD & RGW. We recommend all the users of 12.2.x series update. Notable Changes --------------- *CephFS*: * The CephFS client now checks for older kernels' inability to reliably clear dentries from the kernel dentry cache. The new option client_die_on_failed_dentry_invalidate (default: true) may be turned off to allow the client to proceed (dangerous!). For the full changelog with links, please refer to the release blog at http://ceph.com/releases/v12-2-3-luminous-released/. We thank everyone for contributing PRs, reporting bugs and helping make luminous luminescent. Many thanks to Yuri for keeping the QE runs across the components green.
