Thanks for this great work !

Compared to samba now cifsd is a very attractive alternative for file sharing, without bloat and have RDMA support.

However shadow copy combined with zfs snapshot is an powerful feature for NAS. Do you have any planning to add shadow copy ?

cifsd support shadow copy(windows : FSCTL_COPYCHUNK, linux: copy_file_range(2)). Does it not work well ?

Sorry I'm referring to vfs_shadow_copy2 in order to expose filesystem snapshot as shadow copy.

Hm.. Frankly don't know how to implement the function in the kernel.
