Subject: kobject: Introduce kset_find_obj_hinted.
X-Git-Tag: v2.6.37-rc1~156^2~7
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c25d1dfbd403209025df41a737f82ce8f43d93f5;p=pandora-kernel.git

kobject: Introduce kset_find_obj_hinted.

One call chain getting to kset_find_obj is:
  link_mem_sections()
    find_mem_section()
      kset_find_obj()

This is done during boot.  The memory sections were added in a linearly
increasing order and link_mem_sections tends to utilize them in that
same linear order.

Introduce a kset_find_obj_hinted which is passed the result of the
previous kset_find_obj which it uses for a quick "is the next object
our desired object" check before falling back to the old behavior.
