NFS4 data corruption (client side)
When writing to a file, from time to time some data don't make it to the server. Instead, a hole is left in the file. If the file is opened with O_APPEND, the file pointer jumps back instead and overwrites data.
It only occurs when the file is written with medium speed and the server reacts slow from time to time. A small C-program to reproduce the problem is attached.
The problem is basically that the client accepts r_size updates even though it has outstanding writes.
Webrev to follow.
