From 3991657ae7074c3c497bf095093178bed37ea1b4 Mon Sep 17 00:00:00 2001 From: Anuj Gupta Date: Wed, 26 Jun 2024 15:36:52 +0530 Subject: [PATCH] block: set bip_vcnt correctly Set the bip_vcnt correctly in bio_integrity_init_user and bio_integrity_copy_user. If the bio gets split at a later point, this value is required to set the right bip_vcnt in the cloned bio.
