It is not exactly the problem: When adding an entry, you must update
parent directory mtime/ctime. On NetBSD, the filesystem-independant code
(that is, above VFS) in the kernel does it. On Linux, it seems it is the
responsability of the filesystem (below VFS) to do it.

Since this in-kernel implementation, no standard will tell what OS is
right: both are. The only blame we can put on AFR is that it assumes
Linux behavior, hence the proposal to make it portable.
