Re: [RFC PATCH 1/4] f2fs-tools: simplify get_{sb|cp} and set_{sb|cp}

[Jaegeuk Kim <jaegeuk@kernel.org>]

Hi Sheng,

This is not a good way.
You're asking to change all the pending patches as well.

Why not just adding two definitions like these?

#define get_sb(member)		get_val(sb, member)
#define set_sb(member, val)	set_sb(sb, member, val)
#define get_cp(member)		get_val(cp, member)
#define set_cp(member, val)	set_sb(cp, member, val)

Thanks,
