[PATCH] mm/slub: remove parameter 'flags' in create_kmalloc_caches()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



After commit 16a1d968358a ("mm/slab: remove mm/slab.c and slab_def.h"),
parameter 'flags' is only passed as 0 in create_kmalloc_caches(), and
then it is only passed to new_kmalloc_cache().

So we can change parameter 'flags' to be a local variable with
initial value 0 in new_kmalloc_cache() and remove parameter 'flags'
in create_kmalloc_caches(). Also make new_kmalloc_cache() static
due to it is only used in mm/slab_common.c.
