Please be careful when adding modules. I see that too often new modules
are added without any real need to host this code separately.
There are many examples where this happened. I just noticed:
commands/hdparm.c: struct grub_disk_ata_pass_through_parms apt;
commands/hdparm.c: if (grub_disk_ata_pass_through (disk,&apt))
commands/hdparm.c: struct grub_disk_ata_pass_through_parms apt;
commands/hdparm.c: if (grub_disk_ata_pass_through (disk,&apt))
commands/hdparm.c: struct grub_disk_ata_pass_through_parms apt;
commands/hdparm.c: if (grub_disk_ata_pass_through (disk,&apt))
commands/hdparm.c: if (! grub_disk_ata_pass_through)
disk/ata_pthru.c: struct grub_disk_ata_pass_through_parms
*parms)
disk/ata_pthru.c: grub_disk_ata_pass_through = grub_ata_pass_through;
disk/ata_pthru.c: if (grub_disk_ata_pass_through == grub_ata_pass_through)
disk/ata_pthru.c: grub_disk_ata_pass_through = NULL;
include/grub/disk.h:struct grub_disk_ata_pass_through_parms
include/grub/disk.h:extern grub_err_t (*
EXPORT_VAR(grub_disk_ata_pass_through)) (grub_disk_t,
include/grub/disk.h: struct grub_disk_ata_pass_through_parms *);
kern/disk.c:grub_err_t (* grub_disk_ata_pass_through) (grub_disk_t,
kern/disk.c: struct grub_disk_ata_pass_through_parms *);
this seems unnecessary. ata_pthru is very small. If it's only used by hdparm,
why not just merge it? This also avoids the additional code in kernel.
