From 1e85ddb784375a20e80a60d185998c2753757616 Mon Sep 17 00:00:00 2001 From: "mwleeds@mailtundra.com" Date: Sat, 6 Apr 2024 18:47:28 -0700 Subject: [PATCH] zfs: Fix return value of fs_devread() As evidenced by how other filesystems handle it, a return value of 0 from fs_devread() means failure; nonzero means success. The opposite assumption was being made in zfs.c for the use of zfs_devread() so fix the confusion by making zfs_devread() return 0 on success. It probably doesn't make sense to change the handling of zfs_devread() in zfs.c instead, because as it is it matches the semantics of the other functions there.
