I am pleased to announce the availability of the second rc release of mdadm-4.2, hopefully the last before we cut final. It is available at the usual places: http://www.kernel.org/pub/linux/utils/raid/mdadm/ and via git at git://git.kernel.org/pub/scm/utils/mdadm/mdadm.git http://git.kernel.org/cgit/utils/mdadm/ The update constitutes more than one year of enhancements and bug fixes including for IMSM RAID, Partial Parity Log, clustered RAID support, improved testing, and gcc-8 support.
