From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Robbie Harwood Date: Fri, 15 Jul 2022 15:39:41 -0400 Subject: [PATCH] grub_fs_probe(): dprint errors from filesystems When filesystem detection fails, all that's currently debug-logged is a series of messages like: grub-core/kern/fs.c:56:fs: Detecting ntfs... grub-core/kern/fs.c:76:fs: ntfs detection failed. repeated for each filesystem. Any messages provided to grub_error() by the filesystem are lost, and one has to break out gdb to figure out what went wrong. With this change, one instead sees: grub-core/kern/fs.c:56:fs: Detecting fat... grub-core/osdep/hostdisk.c:357:hostdisk: reusing open device `/path/to/device' grub-core/kern/fs.c:77:fs: error: invalid modification timestamp for /. grub-core/kern/fs.c:79:fs: fat detection failed. in the debug prints.
