Subject: [PATCH] slab: remove alloc_pages() calls
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=50c85a19e7b3928b5b5188524c44ffcbacdd4e35;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] slab: remove alloc_pages() calls

The slab allocator never uses alloc_pages since kmem_getpages() is always
called with a valid nodeid.  Remove the branch and the code from
kmem_getpages()
