[PATCH RT 2/7] mm/slub: move slab initialization into irq enabled region

2015-08-04 Thread Steven Rostedt
3.18.18-rt16-rc1 stable review patch. If anyone has any objections, please let me know. -- From: Thomas Gleixner Initializing a new slab can introduce rather large latencies because most of the initialization runs always with interrupts disabled. There is no point in doing so.
