2010-11-18Documentation: make configfs example code simpler, clearerDan Carpenter
If "p" is NULL then it will cause an oops when we pass it to simple_strtoul(). In this case "p" can not be NULL so I removed the check. I also changed the check a little to make it more explicit that we are testing whether p points to the NUL char.

2008-07-31[PATCH] configfs: Convenience macros for attribute definition.Joel Becker
Sysfs has the _ATTR() and _ATTR_RO() macros to make defining extended form attributes easier. configfs should have something similiar. - _CONFIGFS_ATTR() and _CONFIGFS_ATTR_RO() are the counterparts to the sysfs macros. - CONFIGFS_ATTR_STRUCT() creates the extended form attribute structure. - CONFIGFS_ATTR_OPS() defines the show_attribute()/store_attribute() operations that call the show()/store() operations of the extended form configfs_attributes.
