question about configfs_attribute

question about configfs_attribute

[Constantine Shulyupin]

Hi

I wonder why show and store methods are not stored inside of
configfs_attribute but stored in wrapper struct defined with
CONFIGFS_ATTR_STRUCT ?

Thanks

	If you created a custom attribute struct and methods for
yourself, you would not have to have the show/store methods on the same
structure.  The structure, and the ##item_show/store macros, are a
convenience way to do it.
	It certainly could be done differently.  I cloned the sysfs
approach at the time.  Note that sysfs has a different methodology for
defining attributes now.
