Hi Jens,

we currently have a bug report [1][2] regarding a data corruption with
Samba's vfs_io_uring.c [3].

Is there're a know problem in newer kernels? It seems the 5.3 Kernel
doesn't have the problem (at least Jeremy wasn't able to reproduce it
on the Ubuntu 5.3 kernel).

Do you have any hints how to track that down?

Thanks!
