4 Subject: [PATCH] grub_fs_probe(): dprint errors from filesystems
6 When filesystem detection fails, all that's currently debug-logged is a
7 series of messages like:
9 grub-core/kern/fs.c:56:fs: Detecting ntfs...
10 grub-core/kern/fs.c:76:fs: ntfs detection failed.

16 With this change, one instead sees:
18 grub-core/kern/fs.c:56:fs: Detecting fat...
19 grub-core/osdep/hostdisk.c:357:hostdisk: reusing open device
21 grub-core/kern/fs.c:77:fs: error: invalid modification timestamp for /.
22 grub-core/kern/fs.c:79:fs: fat detection failed.
