Prev: [PATCH -v18 00/37] Use lmb with x86
Next: [PATCH 19/37] x86, lmb: Add x86 version of lmb_find_in_range()
From: Yinghai Lu on 16 Jun 2010 01:50 Also let lmb_reserve_range/lmb_free_range could print out name if lmb=debug is specified will also print ther name when reserve_lmb_area/free_lmb_area are called.
