Subject: mm: cma: print cma name as well in cma_alloc debug
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=35fb4764c8b2cdd91820761eb03c18106d46b8ae;p=tomoyo%2Ftomoyo-test1.git

mm: cma: print cma name as well in cma_alloc debug

CMA allocation can happen either from global cma or from dedicated cma
region.

Thus it is helpful to print cma name as well during initial
debugging to confirm cma regions were getting initialized or not.
