From 0ef2b9e698dbf9ba78f67952a747f35eb7060470 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Mon, 4 Nov 2024 07:26:31 +0100 Subject: [PATCH] block: lift bio_is_zone_append to bio.h Make bio_is_zone_append globally available, because file systems need to use to check for a zone append bio in their end_io handlers to deal with the block layer emulation.
