Subject: [PATCH v2 00/18] lib/stackdepot: fixes and clean-ups
Date: Fri, 10 Feb 2023 22:15:48 +0100 [thread overview]
Message-ID: <cover.1676063693.git.andreyknvl@google.com> (raw)
From: Andrey Konovalov <andreyknvl@google.com>
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.
