[PATCH] slab: reduce inlining
From: Manfred Spraul <manfred@colorfullife.com>
Reduce the amount of inline functions in slab to the functions that
are used in the hot path:
- no inline for debug functions
- no __always_inline, inline is already __always_inline
- remove inline from a few numa support functions.
Before:
text data bss dec hex filename
13588 752 48 14388 3834 mm/slab.o (defconfig)
16671 2492 48 19211 4b0b mm/slab.o (numa)
After:
text data bss dec hex filename
13366 752 48 14166 3756 mm/slab.o (defconfig)
16230 2492 48 18770 4952 mm/slab.o (numa)
