X-Git-Tag: 2.5.57~51
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=cd37ceeab166f467f275619421a735ba5d2b380d

LU-4199 libcfs: Handle nodemask on UMP machines

For UMP and SMP machines the struct cfs_cpt_table are
defined differently. In the case handled by this patch
nodemask is defined as a integer for the UMP case and
as a pointer for the SMP case. This will cause a problem
for ost_setup which reads the nodemask directly. Instead
we create a UMP version of cfs_cpt_nodemask and use that
in ost_setup.
