Subject: sched, cpusets: fix warning in kernel/cpuset.c
X-Git-Tag: v2.6.28-rc7~41^2~1
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1583715ddb61f822041807a0f18b3b4845e88c76;p=pandora-kernel.git

sched, cpusets: fix warning in kernel/cpuset.c

this warning:

  kernel/cpuset.c: In function ‘generate_sched_domains’:
  kernel/cpuset.c:588: warning: ‘ndoms’ may be used uninitialized in this function

triggers because GCC does not recognize that ndoms stays uninitialized
only if doms is NULL - but that flow is covered at the end of
generate_sched_domains().

Help out GCC by initializing this variable to 0. (that's prudent anyway)

Also, this function needs a splitup and code flow simplification:
with 160 lines length it's clearly too long.
