From 4054705215ad7e6dd8e4e6ff27c39abd7667f700 Mon Sep 17 00:00:00 2001 From: Francis Pravin Date: Wed, 7 Feb 2024 05:04:17 +0530 Subject: [PATCH] nvme: use ns->head->pi_size instead of t10_pi_tuple structure size Currently kernel supports 8 byte and 16 byte protection information. So, use ns->head->pi_size instead of sizeof(struct t10_pi_tuple).
