So,
would it be preferable something like this?:
Patch set 1:
- Add <linux/memberof.h> with memberof()
- Split offsetof() to <linux/offsetof.h>
- Split offsetofend() to <linux/offsetofend.h>
- Split typeof_member() to <linux/typeof_member.h>
- Split sizeof_field() to <linux/sizeof_field.h>
- Split NULL to <linux/NULL.h>
- Split ARRAY_SIZE() to <linux/array_size.h>
- Implement offsetof() in terms of memberof()
- Implement typeof_member() in terms of memberof()
- Implement sizeof_field() in terms of memberof()
- Implement container_of_safe() in terms of container_of()
- Remove unnecessary cast from container_of[_safe]()
- Cosmetic changes
Patch set 2:
- And in a different patch set, fix all other files
that make use of these macros.
Patch 1 without editing any other files except for the basic ones,
and adding includes where the definition had been previously,
to not break stuff.
And then,
start patching individual subsystems and
send tiny patch sets to each of them?
For the first part,
I agree it is better.
I'll change it to do that.
I'll send an v2 with less changes and more organized.
For the second part,
I'll see what I can do after the first one has been reviewed.
I'll do tiny patches with a few changes to one or few files,
so that I can reorganize them easily with a rebase -i afterwards,
and then decide.
Thanks,
Alex
