Revision a810007afe239d59c1115fcaa06eb5b480f876e9 authored by Sean Rees on 08 February 2017, 22:30:59 UTC, committed by Linus Torvalds on 08 February 2017, 23:41:43 UTC
Commit 210e7a43fa90 ("mm: SLUB freelist randomization") broke USB hub initialisation as described in https://bugzilla.kernel.org/show_bug.cgi?id=177551. Bail out early from init_cache_random_seq if s->random_seq is already initialised. This prevents destroying the previously computed random_seq offsets later in the function. If the offsets are destroyed, then shuffle_freelist will truncate page->freelist to just the first object (orphaning the rest).
