* src/copyin.c (copyin_device): Don't check for retain_time_flag
|
|
|
|
|
|
global, it's done by set_file_times.
|
|
|
|
|
|
(copyin_link): Call set_file_times to restore symlink times.
|
|
|
|
|
|
* src/util.c (set_perms): Don't check for retain_time_flag global,
|
|
|
|
|
|
done by set_file_times call.
|
|
|
|
|
|
(set_file_times): Do nothing if retain_time_flag global is false.
|
|
|
|
|
|
* src/copypass.c (process_copy_pass): Call set_file_times for
|
|
|
|
|
|
symlinks.
