Race state when moving files on Linux

Suppose I have two scenarios. The first puts (with the mv command) some files into the directory, the second checks the directory once in a while and processes the files. The situation I'm worried about is when the second script starts processing a file that is only partially moving at the moment. Could this happen in real life on an XFS file system?

It depends on where you are moving the files from. mv On one file system, it is atomic, otherwise it must make a copy that is not atomic (followed by the deletion of the original file) and is prone to the kind of race condition that you mention.

FWIW, POSIX, XFS.
