From e4581105771b3523ced88f781eb2672195d217aa Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 12 May 2020 17:55:46 +0900 Subject: block: rename __bio_add_pc_page to bio_add_hw_page Rename __bio_add_pc_page() to bio_add_hw_page() and explicitly pass in a max_sectors argument. This max_sectors argument can be used to specify constraints from the hardware.
