[PATCH 12/22] sysfs: drop kobj and attr from bin related symbols

Tejun Heo
2007-09-20T08:10:58Z

Currently, binary sysfs files are called (kobj) bin attrs. sd-based
interface won't be bound to bin_attribute. Use 'bin' as name and drop
all kobj and attr from symbol names.

This patch doesn't introduce any logic change.
