(diskfs_S_file_utimens): ... new function. * libnetfs/file-utimes.c (netfs_S_file_utimes): Likewise with... (netfs_S_file_utimens): ... new function. * libnetfs/init-init.c: Include . (netfs_mtime): New variable. (netfs_init): New function. * libnetfs/netfs.h (netfs_attempt_utimes): Update documentation. * libnetfs/priv.h (netfs_mtime): Declare variable. * libtreefs/s-file.c (treefs_S_file_utimes): Convert time values and call treefs_s_file_utimens instead of treefs_s_file_utimes. * libtreefs/treefs-hooks.h: Replace TREEFS_HOOK_S_FILE_UTIMES with TREEFS_HOOK_S_FILE_UTIMENS. * libtreefs/treefs-s-hooks.h: Replace s_file_utimes with s_file_utimens. * libtrivfs/file-utimes.c (trivfs_S_file_utimens): New function. * libtrivfs/times.c (trivfs_set_atime): Try to use file_utimens before using file_utimes. (trivfs_set_mtime): Likewise. * nfsd/ops.c (complete_setattr): Likewise. * trans/fakeroot.c (netfs_attempt_utimes): Likewise. * nfs/nfs.c (xdr_encode_sattr_times): Do not set atime or mtime when they are NULL. * configure.ac: Look for file_futimens, and define UTIME_NOW/OMIT, for compatibility with old glibcs. --- doc/hurd.texi | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'doc') diff --git a/doc/hurd.texi b/doc/hurd.texi index e77894a3..7ad798a9 100644 --- a/doc/hurd.texi +++ b/doc/hurd.texi @@ -2722,6 +2722,14 @@ the file.
