Subject: (ST_TIME_CMP_NS, ST_TIME_CMP, ATIME_CMP, CTIME_CMP):
X-Git-Tag: v5.90~203
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b5a377a22b51b69c5b6cc48cb62dedc0040e63d1;p=thirdparty%2Fcoreutils.git

(ST_TIME_CMP_NS, ST_TIME_CMP, ATIME_CMP, CTIME_CMP):
(MTIME_CMP, TIMESPEC_NS): Remove.  Now done by stat-time.h,
in a different way.
(timespec_cmp): New function.
