Bug #3251: file ctime not updated as documented on chmod(), link()
http://bugs.dragonflybsd.org/issues/3251
* Author: tonyc
* Status: New
* Priority: Normal
* Assignee:
* Category: VFS subsystem
* Target version:
----------------------------------------
The stat(2) man page claims:
st_ctim Time when file status was last changed (inode data
modification). Changed by the chmod(2), chown(2), link(2),
mknod(2), rename(2), unlink(2), utimes(2) and write(2)
system calls.
but neither link() nor chmod() update ctim.tv_sec:
$ pwd

$ ./link_ctime
