[fuse-devel] testing of underlying fs in fuse?

[Stef B. <st...@gm...>]

Hello,

I'm working on an overlay fs, and working on an lowlevel version of it.

I do not know how to deal with changes in the underlying fs.
For example a readdir call, this call results in a buffer filled with
dirent types.

Now my fs is able to add entries and inodes (of my fs not the
underlying!) when these do
not exist yet.

But what to do when a file (or a directory) is removed, while there is
an inode and entry
created by my fs for this entry.

Do I have to program it in my fs, everywhere in my fs when it appears
that in the underlying
entries are changed or deleted, or is this done by the VFS subsystem
in the kernel?
