Subject: timezone: If there is no d_type support use fstatat()
X-Git-Tag: 1.6~19
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9dada2fefdb426c6551343a61ca084a22b0d6a1c;p=platform%2Fupstream%2Fconnman.git

timezone: If there is no d_type support use fstatat()

This is useful for filesystems where d_type is always DT_UNKNOWN,
for example reiserfs, jffs2 and ubifs. In this case use the
fstatat() function.
