Subject: [PATCH] Fix partmap, cryptodisk, and abstraction handling in
39700a
 grub-mkconfig.
39700a
39700a
Commit 588744d0dc655177d5883bdcb8f72ff5160109ed caused grub-mkconfig
39700a
no longer to be forgiving of trailing spaces on grub-probe output
39700a
lines, which among other things means that util/grub.d/10_linux.in
39700a
no longer detects LVM.  To fix this, make grub-probe's output
39700a
delimiting more consistent.  As a bonus, this improves the coverage
39700a
of the -0 option.
39700a
39700a
Fixes Debian bug #735935.
39700a
39700a
* grub-core/disk/cryptodisk.c
39700a
(grub_util_cryptodisk_get_abstraction): Add a user-data argument.
39700a
* grub-core/disk/diskfilter.c (grub_diskfilter_get_partmap):
39700a
Likewise.
39700a
* include/grub/cryptodisk.h (grub_util_cryptodisk_get_abstraction):
39700a
Update prototype.
39700a
* include/grub/diskfilter.h (grub_diskfilter_get_partmap): Likewise.
39700a
* util/grub-install.c (push_partmap_module, push_cryptodisk_module,
39700a
probe_mods): Adjust for extra user-data arguments.
39700a
* util/grub-probe.c (do_print, probe_partmap, probe_cryptodisk_uuid,
39700a
probe_abstraction): Use configured delimiter.  Update callers.
