Subject: [PATCH v1 1/7] ACPI: bus: Make container_of() no-op where it makes sense
Date: Mon, 25 Mar 2024 14:32:57 +0200 [thread overview]
Message-ID: <20240325123444.3031851-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240325123444.3031851-1-andriy.shevchenko@linux.intel.com>
Move list head node to be the first member in a few data structures
in order to make container_of() no-op at compile time. On x86_64 with
a custom (default + a few dozens of drivers enabled) configuration:
add/remove: 0/0 grow/shrink: 5/12 up/down: 21/-124 (-103)
...
Total: Before=39924675, After=39924572, chg -0.00%
