ctime/mtime with different filesystems
Hi,
sometimes some tests fails, because mtime/ctime or atime is not
correct set. The problem are the VFS layer and the different filesystems,
they all have a different understand from when which field is to change.
For example, if you truncate a zero length file to zero, VFS only
send a notifier that ctime has to be updated. ext2 will also update
mtime, reiserfs not.
Is there a document describing the behaviour, to which I could point
our filesystem experts ?
