From f705d33c2f0353039d03e5d6f18f70467d86080e Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Wed, 11 Jun 2025 09:59:15 +0900 Subject: [PATCH] block: Clear BIO_EMULATES_ZONE_APPEND flag on BIO completion When blk_zone_write_plug_bio_endio() is called for a regular write BIO used to emulate a zone append operation, that is, a BIO flagged with BIO_EMULATES_ZONE_APPEND, the BIO operation code is restored to the original REQ_OP_ZONE_APPEND but the BIO_EMULATES_ZONE_APPEND flag is not cleared. Clear it to fully return the BIO to its orginal definition.
