Subject: [Linux-ia64] RE: new GPT and uuid patches
Date: Tue, 11 Dec 2001 21:40:26 +0000 [thread overview]
Message-ID: <marc-linux-ia64-105590698805684@msgid-missing> (raw)
In-Reply-To: <marc-linux-ia64-105590698805681@msgid-missing>
> I'll work up a patch.
OK, here goes. New files lib/uuid.c, include/linux/uuid.h. Defines type
uuid_t to be char[16]. Deletes all references to efi_guid_t, replaces
with uuid_t. Patch below and at
http://domsch.com/linux/ia64/linux-2.4.16-ia64-011128-uuid-20011211.patch
This applies after the 011128 patch and the GPT patch submitted
yesterday, it touches fs/partitions/efi.[ch].
There's one drawback I've seen already:
typedef u8 uuid_t[16];
vs
typedef struct _uuid_t {
u8 b[16];
}__attribute((packed)) uuid_t;
You can't have:
uuid_t uuid, *puuid;
as puuid becomes essentially **u8, which isn't what you want.
The only place you see this construct is in drivers/char/random.c, which
I'm not touching at the moment. Need I rework the patch to be a struct
rather than just a flat array of char?
Thanks,
Matt
