SUSE-SU-2016:1696-1

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.59 to receive various security and bugfixes.

Main feature additions: - Improved support for Clustered File System (CephFS, fate#318586). - Addition of kGraft patches now produces logging messages to simplify auditing (fate#317827).
