Subject: basic/mkdir: use timespec_store instead of _nsec for mkdir_p_root_full
X-Git-Tag: v256-rc2~80^2~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=158681f0f97d1efe9c7edf06aa86230964b8d0e6;p=thirdparty%2Fsystemd.git

basic/mkdir: use timespec_store instead of _nsec for mkdir_p_root_full

Follow-up for 34c3d574742e867ef97e79509e4051a82f1b7d9b

O_RDONLY is dropped when O_DIRECTORY is specified, since
it's unnecessary and even arguably confusing here, as
the dir is modified.
