Subject: mm/slab: remove unused slab_early_init
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=35e3c36d438e05fcd4f846c76cf22cbda9b63abb;p=linux.git

mm/slab: remove unused slab_early_init

'slab_early_init' was introduced by 'commit e0a42726794f
("[PATCH] mm/slab.c: fix early init assumption")', this
flag was used to prevent off-slab caches being created
so early during bootup.

The only user of 'slab_early_init' was removed in 'commit
 3217fd9bdf00 ("mm/slab: make criteria for off slab
determination robust and simple")'.
