From: Andrey Konovalov <andreyknvl@xxxxxxxxxx> A set of fixes, comments, and clean-ups I came up with while reading the stack depot code. Changes v1->v2: - Drop "lib/stackdepot: fix setting next_slab_inited in init_stack_slab", as there is no bug to fix. - Use "pool" instead of "slab" for memory regions that store stack traces. - Rename next_slab/pool_inited to next_slab/pool_required and annotate its uses with comments, see new patch #13. - Use STACK_HASH_TABLE_SCALE as a new name for STACK_HASH_SCALE. - Mark stack_depot_set_extra_bits as __must_check. - Only assign extra bits in stack_depot_set_extra_bits for non-empty handles. - Minor comment fixes.
