From ff6369da9ac366f4a18735902ab8f50f5690ee83 Mon Sep 17 00:00:00 2001 From: Kent Overstreet Date: Mon, 26 May 2025 17:15:11 -0400 Subject: [PATCH] bcachefs: reduce stack usage in alloc_sectors_start() with typical config options, variables in different inline functions aren't sharing stack space - and these are slowpaths.
