Subject: b=23072 avoid duplicate cfs_size_round declarations
X-Git-Tag: 2.0.59.0~6
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=0a6e5c9a3060d0145e516f40457a26bd2a3c25db

b=23072 avoid duplicate cfs_size_round declarations

Use HAVE_CFS_SIZE_ROUND to determine if libcfs_private.h or lustre_user.h has
declared the cfs_size_round() helper function.  This avoids conflicts if both
of these headers are included in different orders.
