IIUC, updating mtime for a write is also an attribute change, and that
|
||
|
|
affects ctime. According to the stat(2) manpage:
|
||
|
|
|
||
|
|
The field st_ctime is changed by writing or by setting inode informa-
|
||
|
|
tion (i.e., owner, group, link count, mode, etc.).

Is it exposed to userspace in any (standard) way? It would be handy to
|
||
|
|
have that. While we're wishing...it might also be nice to have a
|
||
|
|
standard way to get at the i_generation from userspace too.
