comparison m4/stat-time.m4 @ 8567:f7fc3652bfc5

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
* lib/stat-time.h (USE_BIRTHTIME): Remove. (get_stat_atime_ns, get_stat_ctime_ns, get_stat_mtime_ns): (get_stat_birthtime_ns): Do not try to use "spare" fields. (get_stat_birthtime_ns): Simplify compile-time tests. (get_stat_birthtime): Change the API to look like get_stat_mtime etc., except return a negative tv_nsec on error. * m4/stat-time.m4 (gl_STAT_TIME, gl_STAT_BIRTHTIME): Don't check for "spare" fields. (gl_STAT_BIRTHTIME): Don't check for struct stat.st_birthtimespec.tv_sec or for struct stat.st_birthtime, as these tests aren't used. * tests/test-stat-time.c (test_birthtime): Adjust to new API.
