From a54fc4932438cfc1f41626d78404237fd5f82e5b Mon Sep 17 00:00:00 2001 From: Tang Yizhou Date: Wed, 9 Oct 2024 23:17:27 +0800 Subject: [PATCH] mm/page-writeback.c: Update comment for BANDWIDTH_INTERVAL The name of the BANDWIDTH_INTERVAL macro is misleading, as it is not only used in the bandwidth update functions wb_update_bandwidth() and __wb_update_bandwidth(), but also in the dirty limit update function domain_update_dirty_limit(). Currently, we haven't found an ideal name, so update the comment only.
